ABSTRACT:
A variable attenuator for optical transceivers such as laser rangefinders for ordnance control. A polarization rotation device, such as a mechanically rotatable half-wave plate or an electrooptic cell, operates in combination with a beam splitter polarizer to attenuate the transmitted laser beam by a continuously variable amount without further attenuating the received laser beam.
