Abstract

A thermal camera having a horizontally disposed linear detector D carries out the vertical scanning of the terrain in the imagery mode and the image D' is brought into the vertical position for carrying out the scanning of the terrain in azimuth in the watch or surveillance mode, the change from one observation mode to the other being obtained by changing the position of an appropriate element of the device, without the interposition of an image rotation element. The array is rotated from a position DAto DB, the imagery and surveillance axes coinciding in the horizontal direction. In figure 6a (not shown), mirror M2is rotated through 90° about the vertical optical axis such that the imagery and surveillance axes are perpendicular to each other in the same horizontal plane; further mirrors may be included to adjust the directions of these axes.
