AUTOMATIC FOCUSING SYSTEM Russian patent published in 1997 - IPC

FIELD: optical engineering. SUBSTANCE: system has range finder including at least one lens and radiator, as well as taking lens coupled to drive which moves it. Drive input is connected to range finder output. System is provided with second drive which turns optical axes of range finder radiating branch relative to taking lens. It has also control panel, light beam splitter positioned behind taking lens, photoreceiving device, mark forming unit, and television monitor. To ensure automatic focusing of moving objects, use can be made of tracking system consisting of lens, two-channel drive and unit which determines object shift relative to optical axis of tracking system. Optical axes of tracking system and range finder lenses are coupled to each other rigidly. EFFECT: more effective design. 12 cl, 3 dwg
