Optical design of a thermal infrared imager for a micro-satellite

Salçın, Esen
Space-based infrared Earth observation systems provide a unique opportunity for the detection of thermal variations on Earth’s surface or atmosphere. The objective of this study is to propose an optical design of a thermal imager that is suitable for flight on a micro-satellite platform at an altitude of 650 km, providing the necessary resolution requirements under the considerations of physical boundaries of the given platform. Before the optical design, the parameters which would strictly bound the optical system such as the infrared source, atmospheric transmission, the detector and optical materials for infrared as well as the working conditions for the microsatellite were examined. Simulations and further optimization efforts resulted with a high performance optical system design.
