Optimized choice of emitting energy of lasers in Transmission Detection Instrument for visual range

本文研究了透射式能见距离测量仪所用激光器的发射能量的优化选择。导出了能见距离、光电转换系统的最小盲区、激光器的发射能量以及仪器与合作目标间的距离四者之间的关系。分别讨论了当光电转换系统的最小盲区及仪器与合作目标间的距离确定时最小可探测能见距离与所需的激光器发射能量的下限、以及当最小可探测能见距离及仪器与合作目标间的距离确定时光电转换系统的最小盲区与所需的激光器发射能量的下限间的关系 ,分析了接收镜头接收口径的大小对所需的激光器发射能量的下限的影响 。

Optimized choice of emitting energy of lasers in transmission detection instrument for visual range was studied.The relationship among visual range,minimum blind area of photoelectric transformation system,emitting energy of lasers and distance from the instrument to cooperation target was gained.The relationship between minimum detectable visual range and required lower limit of emitting energy of lasers at fixed minimum blind area and distance from the instrument to cooperation target,and the relationship between minimum blind area of photoelectric transformation system and required lower limit of emitting energy of lasers at fixed minimum detectable visual range and distance from the instrument to cooperation target were discussed.The effects on required lower limit of emitting energy of lasers by choice of receiving lens diameter were analyzed.A series of reasonable conclusions were obtained.
