Abstract: A corrective device is provided for modulated light transmitters or receivers having light-emitting or light-responsive surfaces for which the modulation phase varies over the surface. The device eliminates any systematic error which may occur where only a portion of the surface is active by providing random reorientation of the transmitted or received light beam, the device taking the form of a multi-path translator wherein light conductors connect points on the input surface of the translator to randomly distributed points on the output surface.

Abstract: An optical rangefinder in which light transmitted to and reflected from a distant object is compared to determine that distance, is improved by providing means to adjust the divergence of the beam of transmitted or reflected light or both to facilitate impingement of the light beam on the object, on the receiver, or both. The improvement is particularly useful in devices which employ a laser light source, particularly a gas laser light source, which transmits a very narrow beam of parallel light.
