ABSTRACT:
An optical system directs the output beam of a light source along a first axis fixed relative to a first support carrying the light source. A second support mounted on the first support is rotated by a first motor about the first axis. A first reflector on the second support is oblique to and always intersected by the first axis. A third support mounted on the second support is rotated by a second motor about a second axis coincident with the reflection of the first axis in the first reflector. A second reflector on the third support is oblique to and always intersected by the second axis. By appropriate energization of the motors the light beam can be reflected in any direction.
