Improved infrared static horizon sensor using an array of thermopiles

摘要

Optoelectronic sensor which can be used in the infrared and comprising an optical system L, F forming the image T% of a target object (for example the Earth) on a detector D. According to the invention, this detector consists of an array of thermopiles tij made on a silicon support which allows integration of means M1, Mc for random-mode access to each thermopile. The sensor does not need cooling and does not require spatial or temporal modulation of the image. Application: terrestrial horizon sensors for artificial satellites. <IMAGE>
