Beam-splitting for optoelectronic image recording

摘要

The invention relates to a device for optoelectronic image recording, preferably with line sensors according to the so-called "push-broom" method. For high geometric resolution, line sensors having a sufficiently high number of discreet individual detectors are required. Under specific circumstances, e.g. for infrared exposures, line sensors are, however, only available with a limited number of individual detectors. The invention presently described shows one way how, by the arrangement of a plurality of reflection surfaces in the focal plane of only one optical main system, the image can be divided into a plurality of partial images and these can be fed without significant beam losses, via corresponding relay optics, to corresponding line sensors of a limited number of detectors and can be scanned. <IMAGE>
