Space activity at Sofradir and new results for hyperspectral detectors

Authors:

Abstract
Sofradir started to work in the field of space applications and especially in the earth observation domain in the beginning of the 1990th. Thanks to the work done with the support of the French Ministry of Defense and the European Space Agency, Sofradir has acquired a large know-how and became a major supplier for European space industry. Sofradir space technologies offer possibilities to develop a large panel of high reliable detectors like long linear arrays or two dimensional arrays covering bandwidth from 0.8 to 15 μm, answering hyperspectral needs, based on qualified Mercury Cadmium Telluride (MCT) technology. Furthermore, Sofradir has a great experience in the field of packaging and offers complete detectors including dewars and coolers. This paper proposes an overview of Sofradir technology capabilities for design of custom space detectors for earth observation or hyperspectral applications, covering the field of detection, hybridisation, readout circuit, focal plane structures, packaging and test. Finally, this paper presents the last results obtained in the development of infrared detectors for hyperspectral instruments.
