2011年浙大光电系光学工程专业复试全过程
2011年浙大光电系光学工程专业复试全过程今年刚考上，把复试经历给大家分享一下，如果以后有机会的话，也可以再联系我，我会尽量帮助大家，因为之前也得到过不少人的帮助，我也是一名外校生，各种消息都比较闭塞，因此也希望这会对大家有些许帮助。
整个复试包括英语听力和专业面试，没有单独的英文面试，只在专业面试时涉及一些专业文献的翻译，下午1:00开始听听力，在一个小阶梯会议室，大约容纳200人，使用多媒体播放;之后是分组面试，今年好像是80进60，分为7组，每组11或12人，应该是随机分的，我在第6组第一个，基本就是1:30开始;无论结果如何，2:00我就解脱了。
一(英语听力:包括两大段、四小段，共22题，全是选择题，老师用手控制各段时间间隔，感觉不好。
大段是两篇interview，每篇5道题，速度还可以，能听到些，感觉能对几个;小段就是对话，速度挺快的，其中的男音很差，就像没吃饭似地，基本是还没听到什么就结束了一段，就这样12个题基本全蒙的，现在记得好像22个题我一个选A的也没有，基本都是选B和C。
二(面试:敲门，进门;桌子对面五位老师，我在复试之前联系的那位老师就是其一，之前曾遇见的另一位老师也在里面，不知其意，有点慌了，这也就是接下来的五位面试官，一般来说中间那位就是主考官，桌子外侧一排椅子，只有中间一个是拉出来的，其余都紧靠桌子，不用想拉到外面的那个就是你的，老师说坐下之后再坐下。
其中有一位应该是记录员，整个过程一句话都没说，还有一位就说了两句，基本全是主考官问的。
自我介绍:三分钟左右，包括个人基本信息、大学所学课程、参加的活动(科技竞赛)、特长(哪门课程)、最大弱点、想从事的方向等。
这个时候很紧张，感觉说话声音都有些发颤，接着自我暗示了一下，之后就好多了，但之后问题又基本都不会了，唉……专业文献: 给你一张纸，平时考试试卷大小，上面有大约七八段不同的专业文献，自己选择一段，先读一遍再翻译，当时我也没怎么细看，就看到右上角一段是关于LCD的，右下角是关于量子力学的，由于复试之前专门准备过各个专业课英文名，所以Quantum Mechanic还是认识的，没敢再看其他的，就说读右下角这段吧。

浙大光学工程研究生入学考试部分复试题目
--------------------------------------------------------------------------------浙江大学光学工程复试参考题目1、激光的全称，其特性和应用激光一词在英文中是“Laser”，是“Light Amplification by Stimulated Emission of Radiation”的缩写，意为“受激发射的辐射光放大”。
特性：（1）单色性：指光强按频率的分布状况，激光的频谱宽度非常窄；（2）相干性：时间相干性和空间相干性都很好；（3）方向性：普通光源向四面八方辐射，而激光基本沿某一直线传播，激光束的发散角很小；（4）高亮度：在单位面积、单位立体角内的输出功率特别大；激光与普通光的根本不同在于激光是一种光子简并度很高的光。
应用：光电技术、激光医疗与光子生物学、激光加工技术、激光检测与计量技术、激光全息技术、激光光谱分析技术、非线性光学、激光化学、量子光学、激光雷达、激光制导、激光分离同位素、激光可控核聚变、激光武器等。
2、望远镜的物镜直径选择根据公式知望远镜物镜的直径影响到一下因素：分辨率、景深直径大则分辨率高，反之则分辨率低；直径大景深小，反之则景深大；3、几何光学的7种误差.单色像差：球差、彗差、场曲、像散、畸变复色像差：位置色差、倍率色差4、全息技术、成像原理、用处全息术是利用“干涉记录、衍射再现”原理的两步无透镜成像法，把从三维物体来的光波前记录在感光材料上（称此为全息图），再按照需要照明此全息图，使原先记录的物光波的波前再现的一种新的照相技术，它是一种三维立体成像技术。
特点：（1）能够记录物体光波振幅和相位的全部信息，并能把他再现出来，应用全息术可以获得与原物相同的立体像；（2）实质上是一种干涉和衍射现象；（3）全息图的任何局部都能再现原物的基本形状。
用处：（1）制作全息光学元件。
全息光学元件实际上是一张用感光记录介质制作的全息图，它具有普通光学元件的成像、分光、滤波、偏转等功能，并有重量轻、制作方便等优点，广泛应用于激光技术、传感器、光通信和光学信息处理等领域；（2）全息显示利用全息术能够再现物体的真实三维图像的特点，是全息术最基本的应用之一；（3）全息干涉计量，例如可用于各种材料的无损检测，非抛光表面和形状复杂表面的检验，研究物体的微小变形、振动和高速运动等；（4）全息存储是一种存储容量大、数据传输速率高和随机存取时间短且能进行并行处理的信息存储方式。

I graduated from the ******* department of *****University in July, xx. In the past two years I have been preparing for the postgraduate examination while I have been teaching *****in NO. ****middle School and I was a head-teacher of a class in junior grade two. Now all my hard work has got a result since I have a chance to be interviewed by you.I am open-minded, quick in thought and very fond of history. In my spare time, I have broad interests like many other youngers.I like reading books, especially those about *******. Frequently I exchange with other people by making ments in the forum on line. In addition, during my college years, I was once a Net-bar technician. So, I have a parative good mand of work application. I am able tooperate the puter well. I am skillful in searching for information on Inter. I am a football fan for years.Italian team is my favorite. Anyway, I feel great pity for our country's team.I always believe that one will easily lag behind unless he keeps on learning. Of course, if I am given a chance to study ****** in this famous University, I will spare no effort to master a good mand of advance ******.Hello, my professors.It's a fine day today,and i'm very pleased to meet you here.First of all,i'd like to introduce myself to you.My name is ***,my hometown is ***,which is a really beautiful city.Even when i was a young boy,i was very interested in biology science.Every one may have a dream,and i still remember that my dream is to be a biology scientist (just like ZHU KE ZHEN).I liked to make wonders just like,where are we from?Where are we going in the universe?And then i would find the answers in book by myself.Still today i think that interest is the best teacher in one's whole life (and knowledge es from practice).Second, i will introduce my major in the university.My major is Biological Engineering in *** University.It has a great relationship with biology scince.Their relationship can be shown with an example: Just like a river,biology science,which often finds new discoveries and theories, is at the head of the river.And my major,which lays more stress on practical use, seems to be at the end of it.When both of them interact well enough,the discovries and theories in biology science can be soon turned into products in all of the modern industry.Four years' university education gives me a lot of things to learn,a lot of chances to try,and a lot of practices to improve myself.It teaches me not only what to study and how to think,but also to see the importance of practicalability (such as doing expriment as much as possible). In the university life,i have made many good friends.They help me improve my study and research ability, do ererythingjust like a man,and often give me good example to follow.Besides what i have introduced myself above,i also have many interests in my spare time.I like playingfootball,which is an effective way i think to improve my body health,and it can teach me how to join in a group and deal with other people.Drawing and writing is another favor to me.Above all,i choose the major in order to broad my view in biology scince,and enhance my research ability.I will do my best to join the new group and be good at postgraduate study.Good morning, teachers, I am honored to be informed to have this interview.Introduce yourselfFirst let me introduce myself, my name is XX, 23 years old, and David is my English name. I am open-minded, easy to adapt, patible with my friends, and willing to help others.Introduce your collegeI studied in XX University.

In a word, I learned a lot in my college life.Introduce your familyIn my family, there are three members, my farther, my mother, and I. My parents are workers, my father works very hard, and he is always fully oupied, so most of the housework is done by my mother, of course, while I am at home, I would help her. I love my parents and they love me, too. When I make a suess, they are more excited than me, and support me to do better. Even though I failed, instead of blaming, they always share sorrow with me, and encourageme not to give up. During my preparation for graduate examination, the support from my family is always my momentum.

中山大学光学工程复试经验贴
中山大学光学工程复试经验贴首先说面试吧，随意性很大，感觉考官都是临时找的{:soso_e138:}。
在一间教室里，6位老师们分散的坐在下面，考生先到旁边一间废弃的教室等候，顺序应该是按照初试成绩排的，这样在开始的时候老师们还有精力的时候可以多看看成绩好点的学生，越到后面人就疲劳了，可能心情也差了，毕竟老师们要工作6个多小时面试掉30多考生（复试名单上是30多个，实际估计只有20个不到），所以初试好才是王道啊。
然后是问题，进去前敲门，向老师们问好。
一开始就直接问英文，3个很简单的问题，name，university，major。
然后是读屏幕上的一段话并翻译，接着他会挑出其中几个词具体问你，是专业相关的内容，难度不是很大。
英语部分就结束了，没有自我介绍，但是不排除下次没有。
然后就是一些闲聊话题：你是应届还是非应届，为什么放弃工作选择考研，工作是干嘛的，做了哪些事，等等（我是非应届的）。
如果是应届的，可能会问你在学校的毕业论文之类的，反正多做下准备如实回答就行了。
接着是专业知识，很基础，只要认真复习了问题应该不大，我记得的几个问题有：你学过哪些主干课程，空间频率是什么，阿贝成像，做过哪些干涉实验，杨氏双缝和迈克尔逊干涉仪分别是测什么相干性，解释下平时我们看湖面特点是远处为倒影近处为湖底现象。
然后，然后就没有了，10分钟很快的一会就好了，这些问题有的衔接比较紧，如果前面答不出来，后面就没了，不过确实很基础，这些问题一定要弄的非常清楚，不能含糊，否则你去忽悠老师就是死路一条。
下面说下笔试，3小时考100分的专业英语和100分的专业课F3007光学工程综合测试，一起做完。
这次笔试变动较大，英语为15道选择题（4分一道），2道计算题(10分一道)，1个自我介绍(20分)；专业课为20道简答题或计算题（5分一道）。
英语改成选择题了，难度骤减，有词义辨析，长句理解，翻译单词几种类型，我把我印象深刻的说一下：1 电流电阻电感电路等的英文2 光强的定义，一句话3 安培表的等级，ammeter grade，没看明白这个4 霍尔效应5 费马原理伯努利原理功能原理计算题就是一个子弹撞木块，一个知道波长求能量自我介绍要求介绍专业及课程专业课，有点难度，覆盖面很广，依然我印象深刻的如下：1 空间频率及阿贝成像2 爱因斯坦的光与物质作用3 激光的几种理论模型（4种）4 复折射率5 激光特点6 激光器基本结构7 反转粒子数形成条件8 空间滤波9 单缝衍射双缝干涉多缝干涉光强计算式，及波形10 影响激光横模的损耗及共同特点11 为什么谐振腔能输出高相干度的激光12 瑞丽判据13 纵模间隔计算驻波计算14 正常色散与反常色散，并利用公式计算15 圆偏光16 时间相干性和空间相干性17 巴俾涅原理好了就这么多了，总是还是要扎实基础，祝各位考生都顺利过关~!复试后记：最后说下考录的情况，今年中大的复试线是300分，很低，但是光工只招收5个人，对！除掉免试的之后只有5个名额，33个人复试，很多炮灰。
研究生英语面试问题及回答
研究生英语面试问题及回答研究生英语面试问题及回答本文五个问题是考研复试英语面试阶段考官常常问到的，各位考生可以参考老师提供的答案范例根据自己的实际情况进行改写，反复熟读，做到发音标准、语法正确、表述流畅，从而在考场上应对自如，回答时可以有适当的`停顿，作思考状，但切忌死记硬背，被考官看出是背的现成答案，就有可能会问一些比较刁钻的问题，不利于考生得分。
所以，建议大家平时多加练习，模拟考场问答，全方位备考。
1、 What is your undergraduate major? How do you like your major?My major is economics. I like my major very much and I quite enjoy my learning journey for the past four years. That’s why I would like to go onto further studies in this area.2、 Why did you choose our university?I choose Beijing Foreign Studies University because of the following reasons. Firstly, it has been my dream place for years as it owns the top quality facilities for language training and the best environment for conducting research in this area. Secondly, I could learn up-to-date knowledge and real world experience to get ready to launch into my chosen career after graduating. Therefore, I could receive a first-class education with a focus on practical skills and professional relevance, giving me excellence prospects for employment and career development.3、How do you plan to study in your postgraduate program?In my opinion, the study method is quite important for research. So firstly, I will choose a certain approach in my study area with your guidance. Then I will draw a pragmatic research plan and time schedule, as I hope that I can form a systematic view of my major. Thirdly, I would familiarize myself with thelatest development of this area by reading books and journals. I do hope that I can get somewhere in this field. If necessary, I will continue my research and study to pursue a doctor’s degree.4、 Why do you change your major for your postgraduate study?I change my major for two main reasons. One is that I am quite interested in economics. In my spare time, I often read books on economics, like An Inquiry into the Nature and Causes of the Wealth of Nations written by Adam Smith, Principles of Economics written by N.Gregory Mankiw, and Intermediate Microeconomics written by Hal Ronald Varian. The more I read those books and relevant articles, the more fascinated I’m in economics. The other is that economics is likely to bring more employment and development opportunities to me than psychology. That’s why I choose economics as my future domain.5、 If there were an opportunity of studying abroad, what would you do?I would like to seize the opportunity for the following reasons. For one thing, I could enhance my overall knowledge and understanding of my subject while exposing myself to English and developing my intercultural skills. For another, I could increase my independence and self-confidence as well as widen my network of friends and future contacts.。

1．光的干涉(Interference of light):若干个光波相遇时产生的光强分布不等于由各个成员波单独造成的光强分布之和，而出现明暗相间的现象。
A number of light waves meet , the light intensity distribution（强度分布） is not equal to separate caused by the various members of the wave intensity distribution and the emergence（出现）of the phenomenon of light and dark .相干条件：只有两列光波的频率相同，相位差恒定，振动方向相同的相干光，才能产生光的干涉。
Coherence [kəu'hiərəns] conditions：Only two light wave frequency（频率）, the phase（相位差） constant（恒定）, the direction of vibration（振动方向）of the same coherent light（相干光）in order to produce the interference of light.（干涉）由两个普通独立光源发出的光，不可能具有相同的频率，更不可能存在固定的相差，因此，不能产生干涉现象。
The light emitted by the two ordinary independent light sources , can not have the same frequency , the less likely there is a fixed（固定的） phase difference , therefore, can not produce interference .2． 光的衍射(The diffraction of light)：光绕过障碍物偏离直线传播路径而进入阴影区里的现象，叫光的衍射。
Light around obstacles to deviate from（偏离） a straight line path into the shadow zone phenomenon , called the diffraction of light .光的衍射和光的干涉一样证明了光具有波动性。
包括：单缝衍射、圆孔衍射、圆板衍射及泊松亮斑Light diffraction（光的衍射）and interference of ligh as that （一样、证明了）the light with the volatility（波动性）.Include: single-slit diffraction , circular aperture diffraction , diffraction of the circular plate and the Poisson bright spot .3． 光的色散(Dispersion of light)指的是复色光分解为单色光的现象It is the phenomenon of the polychromatic light is decomposed / break up/resolve into monochromatic.[,mɔnəukrəu'mætik]（单色的：single colour） .Multicolor['mʌlti,kʌlə]: 多色的在光学中，对于不同的波长，有不同的介质折射率n(λ)，当白光通过三棱镜后，由于棱镜对各种颜色光的偏折程度不同，从而在空间上被分离的现象。
For different wavelengths shows different refractive index n (λ) in the optical medium ，when white light through a prism(棱镜) , due to Prism deflection on a variety of colors of light in varying degrees, resulting in spatial separationphenomenon.一般波长越小，折射率越大；紫色光折射率大，红色光折射率小。
General the smaller the wavelength , the refractive index of the greater ；The purple light refractive index greater than the refractive index of the red light.4 .光的折反射①反射(The reflection of light)：一种光学现象，指光在传播到不同物质时，在分界面上改变传播方向又返回原来物质中的现象。
An optical phenomenon , the light spread to different substances to change the direction of propagation / transmission in the boundary surface returned to the original physical phenomenon .②折射(Refraction [ri'frækʃən] of light)：光从一种透明介质斜射入另一种透明介质时，传播方向发生偏折，这种现象叫光的折射Light slanting（斜射） from a transparent medium into another transparent medium , the propagation direction appears deflection , this phenomenon is called refraction of light.不同之处：光的折射与光的反射一样都是发生在两种介质的交界处，只是反射光返回原介质中，而折射光则进入到另一种介质中。
注意：在两种介质的交界处，既发生折射，同时也发生反射。
反射光光速与入射光相同，折射光光速与入射光不同。
Light refraction and reflection of light are also appear in the joint of two media , but the reflected light returns to the original medium , the refraction of light into another medium.Note: at the joint of the two media , both refraction , but also reflected . Reflected light and the incident light at the speed of light , refraction of light speed is different with incident light .5 .光的偏振(Polarization of light)①线偏振光②圆偏振光③椭圆偏振光④部分偏振光⑤非偏振光（自然光）①Linearly polarized light ②Circularly polarized light ③elliptically polarizedlight ④ partially polarized light ⑤ Natural light光的偏振（polarization of light）振动方向在垂直于传播方向规律性变化的现象。
它是横波区别于其他纵波的一个最明显的标志。
光波电矢量振动的空间分布对于光的传播方向失去对称性的现象叫做光的偏振。
只有横波才能产生偏振现象，故光的偏振是光的波动性的又一例证。
The phenomenon of vibration（振动/shake） direction perpendicular（垂直） to the propagation direction changed regularly.It is one of the most obvious sign of the shear wave is different from other longitudinal wave.Light wave electric vector vibration of the spatial distribution of the direction of propagation of light lost symmetry（对称） of the phenomenon is called polarization of light . Only transverse waves can produce a polarization phenomenon , so the polarization of light is another example of the wave nature of light .6 .光电效应（Photoelectric effect）当光照射到物体上使物体发射电子或电导率发生变化或产生电动势等改变了物体电学特性的现象称为光电效应。
When light shines on the object so that objects emit electrons or conductivity change or generates an electromotive force to change the object of the electrical properties of the phenomenon known as Photoelectric effect .Photoelectric effect can divide into the external photoelectric effect and the internal photoelectric effect . When the phenomenon is produced in surface ,it is called external photoelectric effect , when it happens inside ,we call it internal photoelectric !The internal photoelectric effect includes Photovoltaic effect and Photoconductive effect.7. 空间频率和时间频率（Spatial frequency and time frequency）所谓空间频率是指在一定方向上的单位空间（距离）波动的周期数。
