    摘要: An optical scanning apparatus formed by combining a reflector and a frame in a gimbal construction and having two heart cams held in contact respectively with the reflector and the frame. The heart cams, when rotated each in a fixed direction, impart longitudinal and lateral oscillations to the reflector, enable the incident beam such as of an ultraviolet beam to provide planar scanning of the surface of a given test specimen and, at the same time, permit signals detected in the form of the amounts of oscillations of the reflector to be utilized as output signals for synchronization with a CRT.
