Abstract

A mobile molecular Doppler lidar at an eye-safe 355nm wavelength based on double-edge technique for wind measurement from 10 km to 40 km altitude is being built in Hefei, China. As the key component of the Doppler lidar, the receiver subsystem is designed elaborately. A triple Fabry-Perot etalon is used as the frequency discriminator whose parameters are optimized. The thermal and mechanics stabilities are considered during the receiver design. The designed receiver system is very compact and stable, which could be embedded into a standard 19 inch socket bench with 21 inch length. With this new kind of receiver, the optical alignment is easy and the stability of the etalon transmittance, which is of great importance to the wind measurement, is expected to be improved.
