抄録

A high-speed 3-D camera has a future possibility of wide variety of application fields such as quick inspection of industrial components, observation of motion/destruction of a target object, and fast collision prevention. In this paper, a row-parallel position detector for a high-speed 3-D camera based on a light-section method is presented. In our row-parallel search method, the positions of activated pixels are quickly detected by a row-parallel search circuit in pixel and a row-parallel address acquisition of O (log N) cycles in N-pixel horizontal resolution The architecture keeps high-speed position detection in high pixel resolution. We have designed and fabricated the prototype position sensor with a 128×16 pixel array in 0.35μm CMOS process. The measurement results show it achieves quick activated-position acquisition of 450ns for "beyond-real-time" 3-D imaging and visual feedback The high-speed position detection of the scanning sheet beam is demonstrated.
