Speed-up of range finder system with electronically maskable photo detecting device array

The information of luminance and color at the point where the camera´s sight line hits the surface of object. The area is large at which application of range finder is of useful, for example, model generation for computer graphics [1] and robot´s eye [2]. In order to realize these requests, range finder needs some functions. Especially, there are 3 functions for range finder used for robot control. These are, high-speed measuring to control on a real time, downsizing of equipment, and reducing the cost of the system. The progress of technology, for example, new semiconductor and speed-up of arithmetic processing, meet the demands in recent years but there remains large room for improvement. In our research, we have developed a high-speed range finding system, but some problems have appeared on an implementation process. This paper proposes a solution and an experiment proves it is efficient.
