使用色散法拉第带通滤波器，我们已经升级我们的钠温度激光雷达能够24小时的操作。沿着一个发射望远镜，以减少激光束的发散到0.2毫拉德，这种独特的窄带滤波器在激光雷达接收器中的最初使用，使我们能够减少检测到的白天天空背景的水平以前遇到的夜晚，使日常白天温度测量中层顶区域成为现实。我们认为是第一个白天中层顶温度测量的实施，表征和结果的报告。(C)1996年美国光学学会
Using a dispersive Faraday bandpass filter, we have upgraded our Na temperature lidar to be capable of 24-h operation. Along with a transmitting telescope to reduce the laser beam divergence to 0.2 mrad, the initial use of this unique narrow-band filter in a lidar receiver allowed us to reduce the detected daytime sky background to a level previously encountered at night, making routine daytime temperature measurements in the mesopause region a reality. The implementation, characterization, and results of what we believe are the first daytime mesopause temperature measurements are reported. (C) 1996 Optical Society of America
