Abstract
Abstract An opto-electronic method and switching arrangement for scanning terrain profiles including geometrically and thermally highresolution line scanning apparatuses, notwithstanding their use of known specific sensors with finite time constants, so as to attain a high degree of sensitivity and to furthermore create the possibility to allow for the conversion of an apparatus having a single sensor for the purpose of an increase in its capability, without any extensive requirements. Detector lines are arranged so as to extend in parallel with the scanning direction, and in which there are provided between individual detectors, suitable connecting means in the form of delay elements. An apparatus having single detectors may be converted without the need for an optical corrector or mechanical reconstruction. The delay time may be correlated with the scanning speed of the optical system, or the latter with the delay time of the detector line scanner.
