Wide-Angle Rotating-Mirror Scan System for Use in Laser Display System

摘要

The program covers the design development and fabrication of a wide-angle rotating mirror scanner for use in laser display systems. A hysteresis synchronous motor designed for operation at 300,000 rpm and emplying gas bearings was fabricated and tested. Operation to 240,000 rpm was achieved with ball bearings, while limited success was obtained with gas bearings. In addition, hydrostatic gas-film-lubricated bearings made from copper impregnated tungsten were fabricated and tested. (Author)
