The wide wavelength range is required for obtaining high image resolution, and the high tuning frequency is needed for obtaining video image rates.Thorlabs is pleased to offer a fast sweeping, continuous wavelength, external cavity laser source specifically designed for SS-OCT applications. The standard system sweeps at least 100nm at a 16kHz repetition rate, offers a coherence length of 6mm and delivers more than 12mW of average optical power out of an SMF28 single mode fiber.The laser is available with the following fixed scanning frequency, coherence length and tuning range:■SL1325-P16-16KHz scanning frequency, 6mm coherence length, 120nm tuning rangeThe SL1325 comes with a Mach-Zender interferometer (MZI) with an adjustable free spectral range of 50 to 100 GHz. The MZI is used to digitally resample the raw Optical Coherence T omography (OCT) signal into equally spaced points in frequency. BNC connectors are available to monitor the wavelength sweep direction and laser intensity signals. The SL1325 comes in a 19 inch rack unit configured for 115VAC or 220/240 VAC.OCT is a relatively recent and fundamentally new way of obtaining high-resolution images in turbid media. Various OCT techniques are employed in dermatology, surgery (surgical guidance), and in ophthalmology. One of the driving forces of thedevelopment of the various OCT techniques is to find methods for in-vivo histology. However, the OCT techniques can be used for other types of characterization and visualizing of structures in turbid media, for example, materials research. The development of OCT started in the 1990’s and is a continuously growing field of research and usage.OCT image of in-vivo finger tissue OCT image of in-vivo palm tissueSL1325-P16Sales: 973-579-7227PARAMETERMIN TYPICAL MAX COMMENTSWavelength Range (nm)1265–1385Center Wavelength (nm)131513251340T uning Range (nm) (-10dB cut off point)100–140See models aboveRepetition Rate15–17See models aboveT uning Speed Continuous (nm/ms)–2000–Mean tuning speed around centerwavelengthAverage Optical Output Power (mW)101215Averaged over 1 secondOptical Power Stability (dB)––±0.5Forward to forward scan or backward backward scan during 1 hour usageSignal Source Spontaneous Emission Ratio (SSE) (dB)–25–Optical Isolation (dB)50––Operating Temperature + 10°C –+ 40°C Storage Temperature0°C –+ 70°C Diff.

optical coherence tomography
IntroductionOCT (optical coherence tomography) is a novel noninvasive, noncontact imaging modality which produces high depth resolution (10 microns) cross-sectional tomographs of tissue. It is similar to ultrasound, except that optical rather than acoustic reflectivity is measured. Its value is given by the possibility of achieving pseudo-histological images of the target tissue. It is optically based, analogue to ultrasound B-scan examination and similar to laser reflectometry. Optical coherence tomography involves shining low-level infrared light on a tissue specimen, an interferometer and a computerized imaging system. Because of its high resolution, non-ionizing radiation, etc., in recent years some scholars use it in medical field. This essay will state theory, applications, Advantages and limitations of OCT.System principleLasers transmitting in the chaos medium will be scattering and absorption, and the intensity, coherence and polarization of the light will be changed. According to the number of incidence photons’ scattering, photons can be divided into 3 types: ballistic photon, snake-like photon and scattering photon. Ballistic photons, without scattering through the medium, retain coherence and lots of internal information of scattering medium. Scattering photons have multiple scattering; only bring a small amount of scattering media information. The initial characteristics of the photon are lost, especially coherence. Snake-like photons only have a small number of scattering, transmit with a small incident angle at the direction of axis, retain most of the characteristics of incident photons and have part of structure information of the media. OCT uses the medium information which carried by ballistic photon and the snake-like photon to make image.The core of the OCT system is a fiber-optic Michelson interferometer. Coupling light is transmitted into single-mode fiber. Output is divided by 3dB coupler into two. One of them through the confocal lens system and focused on the sample. The other one through the lens expand and irradiate to the reference mirror. It is used to be reference light. Two beams of light couple and re-join. As Optical path difference less than the coherent light length, the samples of the ballistic light and snake-like light happen to interfere. Interference signal DC circuit transmits through photomultiplier tube and amplifier, collected and processed by a computer. The two-dimensional data we get directly stand for record the organization of the scattering of incident light in samples of the situation regarding the depth and lateral position of function. The results of the data array directly treat as a gray-scale.ApplicationsOptical coherence tomography (OCT) has developed rapidly since its potential for applications in clinical medicine was first demonstrated in 1991. OCT performs high-resolution, cross-sectional tomographic imaging of the internal microstructure in materials and biologic systems by measuring back scattered or back reflected light. Mathematical models have been used to promote understanding of the OCT imaging process and thereby enable development of better imaging instrumentation and data processing algorithms. One of the most important issues in the modeling of OCT systems is the role of the multiple scattered photons, an issue, which only recently has become fully understood; the works of Thrane et al. and Turchin et al. representing the most comprehensive modeling. This technology was used in ophthalmic examination of the retina before. Later, was used for skin and gastrointestinal tract, such as study of incompletely transparent tissues. Until now, we can see the reports of the OCT for the field of stomatology. Colston reported for the first time, in 1998, used OCT technology to get the OCT image of the pig’s premolar dentin and periodontal tissues, Baumgartner in the same year has successful gotten clear OCT images of cementum sector, Amaechi, in 2001, has gotten a typical OCT images of caries tissues. However, these studies are limited to isolated teeth study. Specifically in the future, the success of the OCT detector for nonnasality study will make the OCT images of teeth-in-mouth possible.Results and interpretationsOptical coherence tomography is a new mode of high-resolution tomography, with optical technology and ultra-sensitive detector combined together, application of modern computer image processing, developed into an emerging diagnostic techniques tomography. Since 2001, at the first report of OCT technology in human coronary artery to obtain high-resolution images, the reports on OCT technology in the field of application of percutaneous coronary intervention are gradually increased. Now, the experts all over the world are pay attention to it. OCT has the following advantages: (1) it combines advantages of confocal and weak coherence, optical tomography scan, and has high detection sensitivity and resolution; (2) non-ionizing radiation, safety environmental protection; (3) No damage can be detected; (4) to adopt the optical communications fiber-optic components, it is cheap and portable. However, the shortcomings of the present are: (1) it should not distinguish between the lesion tissues with similar density; (2) incident factors can affect the imaging results; (3) image acquisition time is too long, short term getting a large number of images is still difficult; (4) image analysis software to be further researched and developed, and the lack of different races, different age groups of the normal database.ConclusionBased on the aspects above, it can be concluded that with the rapid development of biomedical Photonics technology, OCT technology will have greater scope for development, technology improvements will focus on the improvement of resolution and imaging depth on the increase. OCT is a young technology. Though it still has little limitations, we can not deny, OCT will become a common and effective means of medical diagnosis.ReferencesFroehly, L & Furfaro, L 2009, ‘Dispersion compensation properties of grating-based temporal-correlation Optical Coherence Tomography systems’, OPTICS COMMUNICATIONS, vol. 282, no. 7, pp1488-1495.Hillman, E &Burgess, S 2009, ‘Sub-millimeter resolution 3D optical imaging of living tissue using laminar optical tomography’, LASER & PHOTONICS REVIEWS, vol. 3, no. 1-2, pp 159-179.Rosenthal, N & Guagliumi, G 2009, ‘Comparison of Intravascular Ultrasound and Optical Coherence Tomography for the Evaluation of Stent Segment Malapposition’, JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY, vol. 53, no. 10, pp A22-A22, NEW YORK.Wolfgang, D & James, G 2008, ‘modeling Light–Tissue Interaction in Optical Coherence Tomography Systems’, Biological and Medical Physics, Biomedical, pp73-115.。

%ABATRACT: Optical coherence tomography (OCT), an imaging system very similar to ultrasound by use of light instead of sound, is an emerging technology for non-invasive, high resolution and cross-sectional imaging based on low-coherence interferometry. In the past, OCT has been widely applied in medical imaging, especially in ophthalmology, cardiology, dermatology and gastrointestinal observation. Yet, its ability to provide three-dimensional tomographic images is also rendering it attractive for applications beyond the medical. In practice, the forensic imaging technology plays an important role in searching, extracting andanalyzing the evidence with merits of non-invasiveness, high speed and high precision. Thus OCT, competent to explore the internal features of an object with micro-meter resolution, will greatly expand the scope of current evidence examination technology, showing a broadly applicable prospect. In this review, we will introduce the basic concepts, principles, categories of OCT technology and a detailed introduction of the so far presented OCT-based methods and applications, ranging from fingerprint imaging, counterfeit banknote detection, easel painting examination, tattoo inspection, bloodstain volume determination, post-mortem interval and bullet imaging. Owing to the characteristic of non-invasive and cross-sectional imaging, OCT is able to detect artificial fingerprint, counterfeit banknote, forgery painting and tattoo. Besides, capable of 3D high resolution imaging, OCT can provide promising applications in high quality imaging and quantitative analyzing, including multi-layer tomography extraction, determination of the volume of bloodstain in the crime scene, image obtainment of the human hair with ultrahigh resolution, estimation of the post-mortem interval and non-contact examination of bullets. Furthermore, OCT techniques have many other advantages as an advanced imaging method with high potential for future forensic applications, for example, the use of near infrared light enabling the non-invasive and non-contact imaging of sample to keep the integrality and authenticity of evidence. Meanwhile, the ability to realize 3D high-resolution cross-sectional imaging will reveal more precise information for sample to authenticate and identify. Moreover, OCT, via extracting differentproperties such as the spectrum, elasticity and polarization, can achieve diversified functional imaging to further improve the image contrast in demonstrating its appropriateness for forensic imaging.【期刊名称】《刑事技术》【年(卷),期】2015(000)005【总页数】8页(P409-416)【关键词】法庭科学;刑事影像技术;光学相干断层成像【作者】张宁;黎智辉;许小京【作者单位】公安部物证鉴定中心，北京 100038;公安部物证鉴定中心，北京100038;公安部物证鉴定中心，北京 100038【正文语种】中文【中图分类】DF793.2光学相干断层成像技术（optical coherence tomo graphy， OCT）是20世纪90年代初发展起来的无损、高分辨、非侵入式的成像技术［1］，是利用生物组织散射光相干原理成像的介观（微米尺度）活体组织高分辨率成像和观测手段。

光学相干弹性成像的图像处理
在基于图像灰度的配准框架下,提出联合刚体变换和B样条的图 像配准方法,实现图像由粗配准到精细配准的过程,提高配准精 度和形变测量范围。为提高计算效率,提出了多级分辨率理论和 基于随机采样的自适应搜索策略。
多级分辨率保证图像不同分辨率级别上的信息得到配准,且减少 了搜索量;基于随机采样的自适应搜索策略避免了手动修改参数, 增强了自适应性。此外,分析不同去噪方法及变换模型对配准结 果的影响,讨论分辨率级数和迭代次数对计算精度和计算速度的 影响,并得出最优的参数设定。
利用图像配准结果,计算组织的位移量,根据纵向位移量得到组 织的应变估计,进而评估组织硬度。实验结果表明,基于图像配 准的OCE弹性成像方法可以估计组织应变,具有较好的临床应用 潜力。
但OCE的图像处理方法仍处于起步阶段,现有的散斑追踪法计算 时间长、测量范围小,相敏检测法稳定性差。因此,本文提出一 种基于图像配准的OCE弹性成像方法。
本文分为OCE图像的获取,图像的噪声分析和去除,弹性成像算法 及算法实现四部分。利用静态施压,获得明胶仿体的OCE图像,分 析OCE系统噪声,提出对应的去噪方法,并利用三种图像质量评估 标准对不同方法的去噪效果进行比较。
光学相干弹性成像的图像处理
生物组织的病理改变常伴随着组织弹性的变化。弹性成像方法 能准确量化组织弹性信息,因而可确定病变的位置,量化分析病 变的性质,为成像技术(Optical Coherence Tomography,OCT) 具有微米级分辨率,可非接触、无损伤地对活体进行三维成像。 基于OCT的光学相干弹性成像技术(Optical Coherence Elastography,OCE)因具有高分辨率、无损伤的优点,有广泛的 应用前景。

薄层扫描应用于眼睛的原理
薄层扫描应用于眼睛的原理1. 简介薄层扫描（Spectral Domain Optical Coherence Tomography，SD-OCT）是一种高分辨率的非接触性光学成像技术，广泛应用于眼科领域。
它通过测量光在组织中的反射或散射来生成高质量的眼底图像。
2. 原理薄层扫描的原理基于干涉技术和光学相干断层成像（Optical Coherence Tomography，OCT）。
下面是薄层扫描应用于眼睛的原理的详细解释：1.光源：薄层扫描使用一种宽带光源，如超连续激光或超短脉冲光源。
这样的光源能够提供宽谱的光，并提供高分辨率的成像。
2.光束分割：通过光学元件，光源产生的光被分成两束，一束用于照明待测物，另一束用作参考光。
其中，照明光束由扫描镜反射并照射在眼部组织上。
3.照明眼部组织：照明光束通过角膜、虹膜、晶状体等透明结构，然后进入眼底组织。
光线在眼底组织中的不同组织结构发生反射或散射。
4.接收光束：反射或散射的光线经过眼部组织，再次通过角膜和晶状体，最后被收集到光学接收器中。
5.干涉：接收到的光线与参考光束相干叠加，形成干涉图案。
这样的干涉图案包含了待测物的反射或散射信息。
6.光谱分析：通过光谱分析，将干涉图案分解成不同深度的信号，形成光学相干断层成像。
这样就可以得到待测物的不同深度的图像，从而生成眼部组织的高质量图像。
3. 优势和应用薄层扫描应用于眼睛的原理具有以下优势：•高分辨率：薄层扫描可以提供高分辨率的眼底图像，能够准确测量眼底组织的细微结构和病变。
•无需接触：薄层扫描是一种无需接触的眼底成像技术，不需要直接接触眼部，减少了对患者的不适感和感染的风险。
•快速成像：薄层扫描可以快速获取眼底图像，一次扫描通常只需要几秒钟，节省了时间并提高了效率。
薄层扫描应用于眼睛的原理被广泛应用于眼科诊断和治疗，具体应用包括：•视网膜疾病的诊断：薄层扫描可以帮助医生准确诊断各种视网膜疾病，如黄斑病变、玻璃体积血和视网膜脱离等。
