Interferometric Optical Filter at 532 nm for Improved Atmospheric and Ocean Measurements with HSRL

Active Technology Project

Project Introduction

Interferometric Optical Filter at 532 nm for Improved Atmospheric and Ocean Measurements with HSRL
Research will begin with selection and testing of candidate materials’ thermal properties and optical properties (NASA Goddard’s CHARMS facility). In parallel, a Structural-Thermal-Optical-Performance (STOP) model of the interferometer will be made to determine the best structural-thermal-optical design. Based on the STOP-optimized design and the sample material thermal and optical data, the component arms of the interferometer will be manufactured to nearly their final lengths, and then measured for Coefficient of Thermal Expansion (CTE) using ASTM-E289. An engineering test unit will be built based on these results, and it will be tested in the Photonics lab for thermo-optical performance/stability and contrast ratio More »
