Abstract
In an apparatus for generating an image of a scene, preferably an image of a heat image, the image is moved line by line across a row of detectors by means of a scanning mirror. The signals thus generated control light-emitting elements via amplifiers. The light-emitting elements are also disposed in a row, and their light is also guided via the scanning mirror. The scanning of the image is done bidirectionally, that is, during the forward pass and return pass of the scanning mirror. For correction of the resultant phase error, which is brought about by a delayed triggering of the light-emitting elements, an optical deflector element is provided which can assume two defined positions. The first position is associated with the forward pass of the scanning mirror and the second position is associated with its return pass and these positions are entirely independent of the location of the scanning lines. The deflector element is preferably in the form of a plane-parallel plate, which is tilted into two angular positions in alternation by means of electromagnets.
