Abstract

We present a holographic lidar system, designed to give complete temperature profiles of the atmosphere. The lidar uses rotational Raman scattering (RRS) from 0-30km and Rayleigh scattering (RS) from 30-100km. The main feature of our lidar is a holographic optical element (HOE) which allows individual lines in the nitrogen rotational RRS to be extracted with high efficiency, along with the Rayleigh return. Due to the effectiveness of the holographic filters we have constructed, our lidar can achieve levels of performance far above existing systems using narrowband filters. The system requires no calibration to radiosondes and has nominal susceptibility to environmental fluctuations.
