INFRARED CAMERA COMPRISING A HIGH-THRESHOLD OPTICAL ZOOM AND CORRESPONDING METHOD OF OBSERVING A SCENE

摘要

The invention relates to an infrared camera comprising an optical zoom, characterized in that it comprises: a matrix detector (5) comprising a cooled screen, a matrix able to detect infrared radiation; a module (123) that modifies the focal length of the camera, the modifying module being able to vary the focal distance of the camera to ensure the optical zoom function of the camera; and- an imaging module (L4) capable of ensuring, for all the focal length values of the camera: on the one hand, the focusing of the infrared radiation on the matrix of the detector, and on the other hand the conjugation of the pupil of the camera The invention also relates to a method of observing a scene with the camera according to the invention.
