Title (EN) OPTICAL SYSTEM FOR THERMAL IMAGER
(FR) SYSTÈME OPTIQUE POUR IMAGEUR THERMIQUE
Abstract:
(EN) The invention relates to an optical system with mirrors for an image sensor, comprising two symmetrical concave mirrors (20a, 20b) arranged in the same plane and having parallel optical axes (Oa, Ob); and a matrix image sensor (24) arranged in front of the mirrors and having two opposing edges which are respectively substantially adjacent to the optical axes of the two mirrors. The image sensor can be attached to an opaque cache (28) comprising, on the periphery of the image sensor, an entrance pupil (26) in front of each mirror (20), contained in the surface of the mirror extending beyond the image sensor.
(FR) L'invention est relative àun système optique à miroirs pour un capteur d'image, comprenant deux miroirs concaves (20a, 20b) symétriques situés dans un même plan et ayant des axes optiques parallèles (Oa, Ob); et un capteur d'image matriciel (24) situé devant les miroirs et ayant deux bords opposés sensiblement adjacents respectivement aux axes optiques des deux miroirs. Le capteur d'image peut être fixé sur un cache opaque (28) comprenant, à la périphérie du capteur d'image, une pupille d'entrée (26) devant chaque miroir (20), contenue dans la surface du miroir débordant du capteur d'image.
