METHOD OF ATHERMALIZATION OF AN OPTOELECTRONIC SYSTEM AND ATHERMALIZED OPTOELECTRONIC SYSTEM

摘要

The athermalized optoelectronic system (1) comprises an optical device (2) exhibiting a focal plane (4) and a detector (5) cooperating with this optical device (2) and comprising a detection matrix (6) which exhibits a stable orientation with respect to said focal plane (4), as well as means of mechanical linking (7) between the optical device (2) and the detector (5), which exhibit expansion properties making it possible to compensate for a law of relative expansion between the optical device (2) and the detector (5), which is determined on the basis of at least one law of expansion of the optical device (2) and of at least one law of expansion of the detector (5), an expansion law indicating the displacement due to expansion as a function of temperature.
