Abstract
Michigan Aerospace Corporation (MAC) is pleased to present the following Phase II proposal for a Fabry-Perot Based Interferometer Receiver for the High Spectral Resolution Lidar (HSRL) System. Under the Phase I work, MAC successfully developed instrument models and created a conceptual design for an aircraft-qualified receiver that can be used with the current HSRL collection optics. This design is optimized to spectrally separate the aerosol and molecular backscatter for the calculation of the aerosol-to-total-scattering ratio and aerosol extinction coefficient. Additionally, wind and temperature data products can be produced with this system. The proposed Phase II efforts are directed at designing and building a bench-top HSRL 532nm receiver that is capable of taking accurate measurements of aerosol scattering ratio, extinction coefficients, molecular temperature and line-of-sight (LOS) velocity. This demonstration unit will verify a new adaptive interferometer measurement technique, called the Programmable Edge Technique (PET), which makes use of a Digital Micro-mirror Device (DMD) in conjunction with a Fabry-Perot interferometer and two photo-multiplier tubes (PMT). The completed bench-top receiver design will serve as the baseline for future aircraft mounted implementations.
