光探测或光电转换在自动化、过程控制等领域中有着广泛的应用。为接收或探测信号光束或瞬时光脉冲而设计的任何一种系统几乎不可避免的都处在环境光的影响之下。这样,就存在着一个如何提高和增强系统的接收灵敏度及抗杂散光干扰能力的问题。特别是当有用的光信号比较微弱而且是一种瞬时光脉冲的情况下,这个问题更为突出。为要解决这一问题,我
Optical detection or photoelectric conversion in automation, process control and other fields have a wide range of applications. Any system designed to receive or detect a signal beam or an instantaneous light pulse is almost inevitable under the influence of ambient light. In this way, there is a problem of how to improve and enhance the system’s receiving sensitivity and anti-stray light interference ability. This problem is especially noticeable when the useful optical signal is weak and an instantaneous light pulse. In order to solve this problem, I
