Abstract

An optoelectronic viewing system for imaging a field of view on a monitor includes a telescope for generating an optical image of the field of view, a scanning device for electronically scanning the optical image and an electronic evaluation unit for processing the scanning signals and displaying the image on the monitor. In order to create a field of view which is large enough for surveillance with a long-range viewing system that has sufficient resolution, a mirror system for pivoting the direction of beam incidence in the vertical and horizontal direction is placed ahead of the telescope. The mirror system is driven for reproducibly and consecutively passing through a succession of fixed predetermined pivoted positions. The scanned image signals obtained from the individual pivoted positions are combined into a field of view. In one embodiment, a small field of view contained within the large field of view, which can be positioned as desired within the large field of view and which is generated by a second telescope utilizing the same image scanning device and the same evaluation unit, can be displayed in parallel thereto.
