An Optimized Interferometer for HSRL Applications

Completed Technology Project

Project Introduction

Develop interferometric High Spectral Resolution Lidar (HSRL) receiver component technology that will reduce mass, power, volume, risk, and cost for the Aerosols-Clouds-Ecosystems (ACE) Decadal Survey mission.  This interferometer will be a significant advance over the current HSRL-2 interferometer:
More robust frequency locking (one degree of freedom vs. 3 in current design)
Higher long-term calibration stability (increased accuracy in science retrievals)
Allows simpler supporting detectors, electronics, and frequency locking architecture
