摘要

An arrangement for optically measuring angles between two approximately paralle. optical axes (2,11) contains an arm (3) pivotable about the first axis (2) with a rotary bearing (4) and associated beam dividers (6,7) adjustable about three mutually perpendicular axes. One divider is movable along the carrier arm. The distance between the axes intersections with the focal plane of an autocollimation camera (1,2) is a measure of the angle between the camera optical axis (2) and a targetting device sight line (11). USE/ADVANTAGE - Measuring angle between auto-collimation camera optical axis and targetting device sight line with self-adjusting arrangement.
