Optical proximity sensor that uses a laser-scanning system.
An optical-sensor scheme that uses a conically scanned laser-beam spot is proposed and discussed. An algorithm for distance and orientation measurements is used together with numerical-analysis techniques to measure distance to an accuracy of +/- 1 mm and orientation to +/- 1.50 degrees . The system's applications for robotic arm manipulators are discussed.
