Design of a monolithic Michelson interferometer for fringe imaging in a near-field, UV, direct-detection Doppler wind lidar.
2016
The low-biased, fast, airborne, short-range, and range-resolved determination of atmospheric wind speeds plays a
key role in wake vortex and turbulence mitigation strategies and would improve flight safety, comfort, and
economy. In this work, a concept for an airborne, UV, direct-detection Doppler wind lidar receiver is presented.
A monolithic, tilted, field-widened, fringe-imaging Michelson interferometer (FWFIMI) combines the Advantages of low angular sensitivity, high thermo-mechanical stability, independence of the specific atmospheric conditions, and potential for fast data evaluation. Design and integration of the FWFIMI into a lidar receiver concept are described. Simulations help to evaluate the receiver design and prospect sufficient performance under different atmospheric conditions.
