瑞利散射测风激光雷达接收机的研究

Development of Rayleigh Doppler wind lidar receiver

介绍了分子散射多普勒测风激光雷达的基本原理。优化了三通道法布里-珀罗标准具的自由谱范围、带宽、峰值间隔和有效口径等参数。设计了分子散射多普勒测风激光雷达接收系统的结构,设计时充分考虑了系统的热稳定性和机械结构的稳定性。该接收机结构非常紧凑,可以放置在宽度约48cm(19in)、长度550mm的机柜中。具有这种接收机的多普勒测风激光雷达具有很好的商业应用前景。

Principle of molecular Doppler wind lidar is introduced. The parameters of triple Fabry-Perot etalon, namely, free spectral range, spectral width, peak offsets between each etalon, effective aperture and so on are optimized. The structure of molecular Doppler wind lidar receiver is designed detailedly. The stabilities of temperature and mechanics are considered in its design. The designed receiver is very compact and could be embedded into a standard 19 inch socket bench with 550 mm length. Doppler lidar wi...
