HIGH RESOLUTION INFRARED IMAGE FORMATION METHOD AND THERMAL CAMERA WITH SINGLE-DIRECTIONAL SCANNING FOR USE THEREOF.

摘要

The invention relates to a thermal camera with unidirectional scanning and a signal sampling method for such a camera. The thermal camera according to the invention includes an afocal entrance optic system (1), a scanning mirror (2) for line by line scrolling of an image of the scene, this image being projected by an objective (3) onto a detector (4). The sampling increment of the detector (4) has a value of between one half and three-quarters the value of the average side of the elementary detecting surfaces, organised in a line, of the detector (4). A line memory (11) is mounted ahead of the video processing circuit (9) so as to use a line length matched to the angular offset caused by the vibrations in the horizontal direction and registered by a gyroscope (13). Application to the formation of high-resolution images within the infrared. IMAGE
