Abstract: A laser Doppler velocimeter employing a compact disc pickup for both fringe projection and signal detection is described. The spectrum of the recorded signal gives the information about the speed of the object. The device takes advantage of the Talbot effect to project the grating contained in the pickup onto a moving target,so that no imaging system is required. The peculiar imaging technique allows for the exploitation of several optical configurations and permits the manipulation of the intensity profile of the projected grating. The instrument was used to measure the velocity of dust particles on a solid substrate in the 1-m/s range but could also find an application to the study of liquid flow.
