In this paper, a high-speed range image sensor using a multi-spot laser projector is constructed. Several highspeed range image sensors have been developed recently. Their sampling rate is around the video rate (30Hz or so) and a faster sensor is required. The proposed sensor has achieved 200Hz measurement. It consists of a commercially available laser projector and a high-speed CCD camera. The number of pixels is 361 and the measurement range is 800-2000mm. Although the acquired range image is
