Abstract

Bei einer Vorrichtung zur Abtastung eines Gesichtsfeldes mittels auf elektromagnetische Strahlung ansprechender Sensoren, insbesondere zur Beobachtung eines Geländes mittels eines unbemannten Flugkörpers (Bilddrohne), ist das Gesichtsfeld mittels einer Mehrzahl von Abtaststrahlengängen mit je einem eigenen optischen System (12,16,20) abtastbar, und sind die Abtaststrahlengänge zur Erzeugung einer Abtastbewegung durch ein gemeinsames Ablenksystem (22;40) in gleicher Weise ablenkbar. Die Abtaststrahlengänge überlappen sich im Bereich des abzutastenden Gesichtsfeldes wenigstens teilweise. In mehreren Abtaststrahlengängen sind Bereiche des abzutastenden Gesichtsfeldes durch die jeweiligen optischen Systeme (12,16) auf je einen Sensor (10,14) abbildbar. Die Sensoren (10,14) sind in unterschiedlichen Spektralbereichen empfindlich. In einem der Abtaststrahlengänge ist ein Bereich des abzutastenden Gesichtsfeldes mittels eines Lasers (18) beleuchtbar. In einem anderen Abtaststrahlengang ist durch das optische System (16) wenigstens ein Teil des so beleuchteten Bereiches auf einen für die Strahlung der Lichtquelle (18) empfindlichen Sensor (14) abbildbar ist.

Figure 00000001
In a device for scanning a field of view by means of sensors responding to electromagnetic radiation, in particular for observing a terrain by means of an unmanned aerial vehicle (image drone), the field of vision can be scanned by means of a plurality of scanning beam paths, each with its own optical system (12, 16, 20), and the scanning beam paths for generating a scanning movement can be deflected in the same way by a common deflection system (22; 40). The scanning beam paths overlap at least partially in the area of the visual field to be scanned. Areas of the field of view to be scanned can be imaged in a plurality of scanning beam paths by the respective optical systems (12, 16) on a respective sensor (10, 14). The sensors (10, 14) are sensitive in different spectral ranges. A region of the visual field to be scanned can be illuminated in one of the scanning beam paths by means of a laser (18). In another scanning beam path, at least a part of the area illuminated in this way can be imaged on a sensor (14) sensitive to the radiation from the light source (18) by the optical system (16).
