Aircraft deployable UV-SWIR multiangle spectropolarimetric imager (AirMSPI-2)

Completed Technology Project

Project Description

The Aircraft Deployable UV-SWIR Multi-angle Spectro-polarimetric Imager (AirMSPI-2) will develop multi-line UV/VNIR/SWIR detector and read-out integrated circuit (ROIC) that operates at high speed (25 Mpix/sec), has low noise, and can meet precise synchronization requirements of a Photoelastic Modulator (PEM) based camera. The project will integrate the focal plane assembly with miniaturized spectropolarimetric filters bonded to the hybridized detector array. Partner with Teledyne Imaging Sensors to develop HgCdTe (mercury cadmium telluride) detector bump-bonded to a custom ROIC. Develop focal plane assembly to host the detector/ROIC, spectropolarimetric filters, and thermal system compatible with the camera, a gimbal, and the NASA ER-2 aircraft. Construct AirMSPI-2 by installing newly developed SWIR and UV/VNIR focal planes in the 4-mirror telescope developed under previous effort. More »
