1.问题的提出并扫是红外扫描系统一种重要的扫描方式。如何将同时获取的若干条并行的视频信号,在规定的时间内转换成电视格式的逐次扫描线,就是采用这种扫描体制所涉及到的多路传输技术,即将若干个通道压缩为一个通道的技术。通常是利用电子多路开关或称为时分制多路开关的方法来实现的。在每一次扫描时间内,它顺序地对每个探测器进行采样,并周
1. The issue of scanning and scanning is an important scanning method of infrared scanning system. How to obtain several parallel video signals in a specified period of time into the TV format of successive scanning lines is to use this scanning system involves the multiplexing technology that will be a number of channels compressed into a channel technology. This is usually done using electronic multiplexers or time-division multiplexed switches. Within each scan, it samples each detector sequentially, and weeks
