Abstract

See full text

A moving body measuring apparatus which can measure a distance and/or an azimuth angle to a moving body using a laser beam in a minimized measuring cycle with a simplified scanning mechanism under a minimized influence of a disturbance of the background light or the sunlight. Laser light is first shaped into a fan beam by expanding the same in a first direction by a fan beam shaping optical system. The fan beam is deflected in a second direction perpendicular to the first direction to scan by a uniaxial light scanning mechanism and is irradiated upon a target. Reflected light of the fan beam is deflected by the uniaxial light scanning mechanism and introduced into an optical detector by way of a light receiving optical system.
