Abstract
In this study, a beam scanning Laser Doppler Velocimeter (LVD) system for measuring velocity profiles of unsteady flow, in which the point of measurement is controlled by rotating mirrors, is described. A prototype system has been constructed and tested. The use of a microcomputer to control the angles of the mirrors allows a high scan rate to be achieved. The time to measure a velocity profile is 0. 13 sec. and the system can measure the profile of oscillatory flows up to the frequency of 0. 12 Hz within the accuracy of 5%.
