  本文针对地震后救援现场光照度低、温度变化复杂等特点,设计一款视觉生命探测系统,该系统主要由图像采集、图像传输、图像处理及显示、系统控制四模块构成。当救援现场光照度≥10Lux时,系统对救援现场进行可见光图像采集;当救援现场光照度<10Lux时,采用红外主动探测方式,即系统近红外光源打开,CCD 接收救援现场反射的近红外光并将其转化为图像信号。同时,为提高救援现场环境成像的信噪比,系统中图像处理模块对采集的图像进行相应图像处理。该系统可实现低照度下震后救援现场的高清晰成像要求,为救援人员制定高效可行的救援方案提供决策依据。

本文在分析光波偏振特性的基础上,提出偏振移位键控(PoISK)技术,即对激光偏振态参数进行调制/解调的技术。文中构建了基于圆偏振移位键控(CPoISK)的平衡探测大气激光通信系统,利用圆偏振光的两种旋态(左旋和右旋)进行编码通信。并对OOK 系统与单路接收PoISK 系统、平衡探测CPoISK 系统进行计算机仿真,对比、分析各通信系统性能。结果表明:偏振移位键控技术在自由空间光通信领域具有独特的优
