论文部分内容阅读
本文以及在本讲习集前面我们所写的另一篇文章,对典型的电子光学系统的设计,从系统的角度进行了讨论。前视红外系统,与前面那篇文章所描述的系统不同,它是一种被动传感器系统。本文根据基本原理,推导了设计公式,着重论述了各个量的物理意义;论述和分析了系统设计过程,特别着重论述了设计时所进行的折衷;阐述了在设计中使用背景限(Blip)探测器的好处;举例阐明了典型系统设计的程序。
This article, as well as another article we wrote earlier in this workshop, discusses the design of a typical electronic optical system from a system perspective. The forward looking infrared system, unlike the system described in the previous article, is a passive sensor system. Based on the basic principle, this dissertation deduces the design formula, emphasizes on the physical meaning of each quantity, discusses and analyzes the process of system design, especially focuses on the trade-off during design time, expounds how to use the Blip detection in the design, The benefits of the device; illustrate the typical system design procedure.
