ABSTRACT:
An improved thermal imaging device is provided herein, which includes an internally-mirrored autocollimating mirror, a multi-element detector and a diaphragm in the mirror for limiting the aperture of the multi-element detector. In the improved device the multi-element detector is offset from the optical axis. At a symmetrical point on the other side of the optical axis, at which the autocollimating mirror forms an image of the multi-element detector, a mirror is disposed. Such mirror project the image of the multi-element detector back to the autocollimating mirror. Such image is then reflected once more right way up and laterally unreversed onto the multi-element detector in such a way that each individual detector element receives its own image.
