Beam projector |
摘要 |
A beam projector is provided by a plurality of coded reticles mounted on a spinning disc and illuminated by a laser source. In order to maintain a constant irradiance on a receiver variably located in space a pseudo-zoom assembly is provided including a moveable source and/or condenser optics. Also, plural focal length optics are employed to expand the range over which the constant irradiance is maintained beyond that realizable by the pseudo-zoom assembly itself.
