Abstract:

Methods were investigated for a wide angle deflection of a laser beam at rates compatable with standard video processing. The effort consisted of investigation and design of a magnetic suspension and rotation device for achieving scan rates in excess of 3,000 revolutions per second. Two design Q coil and differential pickup approaches were investigated and measurements were made of rotational rates and acceleration verses input drive power. Stability was investigated under short term conditions for different rotor configurations, and special measures were undertaken to minimize drift of the supported body. One of the designs, namely the differential pickup type, appears worthy of further investigation and testing.
