法拉第反常色散滤光器用于空间光通信系统的实验研究
Experimental Research on the Use of Faraday Anomalous Dispersion Optical Filter in Space Optical Communication System
【摘要】 首次把法拉第反常色散滤光器(FADOF)用于空间光通信系统。在强太阳光背景下,成功地进行了DPPM方式的图象传输实验。结果表明,其检测灵敏度比用干涉滤光片(IF)时提高了约23倍。
【Abstract】 Faraday anomalous dispersion optical filter (FADOF) is applied to space optical communication system for the first time. On strong solar background, image is transmitted and received successfully by means of digital pulse position modulation (DPPM) mode. The result shows that the sensitivity of receiver using FADOF is about 23 times better than that of receiver using interference filter (IF).
