A method for high speed 3-D range measurement and its trail instrumentation

A system based on slit-ray projection method is presented that uses a nonscanning type image plane. It consists of a 2-D array of discrete photodetectors, attached to an individual memory element. The whole system is designed to latch positional information of a slit-ray into the memory when the cor...

More Information
Summary:A system based on slit-ray projection method is presented that uses a nonscanning type image plane. It consists of a 2-D array of discrete photodetectors, attached to an individual memory element. The whole system is designed to latch positional information of a slit-ray into the memory when the corresponding photodetector is triggered by slitlike image passing across the image plane. Basic data for range computation are acquired during only one scanning of slit-ray. Trial implementation of this system has verified the method to be effective, showing data acquisition time within a few milliseconds.< >
