Coherent optical methods are described for application in the artificial visual sensing function of robot systems. Prior methods for scene measurements are reviewed. A new approach based on the coherent properties of laser radiation for the quantization of the scene is presented. The results from a prototype optical system are presented, and several potential features for further development are discussed.
