Thermal Compensator for Paraboloidal Reflector
Mounting structure holds off-axis paraboloidal collimating mirror so that optical axis constantly focused and remains stationary with respect to fixed point over wide temperature range.

Design study for Thermal Infrared Multispectral Scanner (TIMS)
The feasibility of dividing the 8-12 micrometer thermal infrared wavelength region into six spectral bands by an airborne line scanner system was investigated. By combining an existing scanner design with a 6 band spectrometer, a system for the remote sensing of Earth resources was developed. The elements in the spectrometer include an off axis reflective collimator, a reflective diffraction grating, a triplet germanium imaging lens, a photoconductive mercury cadmium telluride sensor array, and the mechanical assembly to hold these parts and maintain their optical alignment across a broad temperature range. The existing scanner design was modified to accept the new spectrometer and two field filling thermal reference sources.
