Abstract
An optical observation device for observing a target located at a distant observation sight that comprises an observation telescope and an infrared sighting device. The infrared sighting device eventually provides a visual target image as a sighting marker from a thermal infrared image of the observation sight. The sighting marker and the observation sight are simultaneously viewed in the field of view of the observation telescope so as to enable training of the observation telescope on a part of the observation sight where the target is located.
Claims24
An optical observation device for field observation of an observation target staying in a forward observation sight, comprising:
- an optical telescopic means situated on one of a pair of parallel optical axes for producing a visible image of the forward observation sight and allowing observation of the forward observation sight therethrough;
- and
- an infrared sighting means situated on the other of the pair of parallel optical axes and optically coupled to the optical telescopic means,
- wherein the infrared sighting means generates a visible image of the observation target from an infrared image of the forward observation sight and spatially displays the visible image of the observation target in an image focus location of the optical telescopic means so as to superimpose the visible image of the observation target as a sighting marker on the visible image of the forward observation sight for simultaneous observation of both the visible images of the observation target and the forward observation sight through the optical telescopic means.
