非制冷红外热像仪简述

摘要：非制冷红外热像仪是目前主流的夜视观察仪器之一,因其较高的可靠性在军事领域的低端应用、民用等方面有广阔的前景。它通过被测物体向外界发出的辐射能量来得到物体对应的温度。本文主要就非制冷红外热像仪的测温原理、发展状况、系统设计及其性能参数做简单的分析及介绍。比较了两种不同情况下的测温公式的优劣并且做出了相关推导，简单介绍了基于FPGA的非制冷红外热像仪的电路系统和通用型非制冷红外热像仪的性能参数及其一般测定方法。对以后的红外热成像系统的学习起到了一定帮助。

The brief description of uncooled infrared thermal imager Yu Chun-kai, Wang Hui-ting, Qi Xiao-yun, Xu Jian

Abstract: Currently, uncooled infrared thermal imager is one kind of mainstream devices on night vision. Because of its high reliability, uncooled infrared thermal imager has a broad prospect of application in military and civil field. It gains temperature of the detected object by the infrared radiation the object emits. This paper simply analyses and introduces temperature measuring principle, development status, system design and performance parameter on uncooled infrared thermal imager. We compared two different temperature measuring formulae in their respective situations and did the relevant derivation. We also introduced the circuit system which based on FPGA in uncooled infrared thermal imager and the performance parameter of general uncooled infrared thermal imager. This paper provides us much promotion about the future study of infrared thermal imaging system.

Key words: uncooled infrared thermal imager; temperature measuring principle; development status; system design; performance parameter
