24 August 1987 Electro-Optically Slaved, Forward-Scatter Receiver/Traverse System For Laser Velocimetry*

Electro-optical position sensing and position control system techniques have been combined to precisely couple the 2-axis motions of a slave traverse system to the 2-axis motions of a master traverse system. This scheme is used to implement a laser Doppler velocimeter (LDV) optical system in the forward-scatter configuration. The slaved traverse approach is useful for LDV applications in large aerodynamic or aeropropulsion testing facilities where a yoke assembly for diametrically positioning the LDV transmitter and receiver may be impractical. The slaved traverse system has, to date, been used successfully for LDV measurements in a large transonic wind tunnel and a large supersonic wind tunnel at AEDC.
