ALIGNING OF OPTICAL DEVICES

摘要

The invention is illustrated, as an example, by a sniper situation. A sniper's eye 16 observes a target 12 via an aligner 20, and a beam splitter 24 along a line of sight 14. The beam splitter 24 projects the image 12 onto a charge coupled video camera 18 which shows the image on a monitor to a controller of the sniper. A frame 22 ensures that the camera 18 and the beam splitter are directed along a line of sight in constant relation to the frame. If the eye 16 deviates from the line of sight of the camera, the image seen by the eye 16 is affected and the sniper can adjust. The aligner 20 has a plurality of narrow, straight, sight passages surrounded by walls. Misalignment of the eye 16 causes partial obscurement, which is progressive with the angle of misalignment, of the image.
