一、前言作为一个红外观察系统,最起码有几个因素是应该考虑的:(1)系统的观察视场;(2)系统的观察距离;(3)系统的精度。当然,还应考虑到:系统的观察环境条件(即一定背景条件下目标的探测,环境的温度和湿度等);所观察目标的种类;系统制作的难易;系统工作的可靠性;系统的体积和重量、经济效益等等。提到红外观察系统,人们理所当然的想到使用热成象技术。因为它可获得目标景物的实时图象,给观察者以实感。它的置信度远远高于利用指示灯、或仪表指针、或人工影象等显示方式的红外观察装置。对于航空机载观察,其优越性更为突出。
I. INTRODUCTION As an infrared observation system, there are at least several factors that should be considered: (1) systematic observation field of view; (2) systematic observation distance; (3) systematic accuracy. Of course, it should also take into account: the observed environmental conditions of the system (ie, the detection of targets under certain background conditions, the temperature and humidity of the environment, etc.); the type of target observed; the difficulty of system fabrication; the reliability of system operation; Volume and weight, economic benefits and more. When it comes to infrared viewing systems, it is natural to think of using thermal imaging techniques. Because it can get the real-time image of the target scene, give the observer a sense of reality. Its confidence is far higher than the use of light, or instrument pointer, or artificial visual display infrared observation device. For airborne observations, its superiority is more prominent.
