Holographic three-dimensional vision of robots

A new method for constructing a three-dimensional vision system for robots is based on acquisition of a focused-image hologram of a real scene using radiation with a suitably selected temporal coherence function. The intensity of the reconstructed signal from each point of such a hologram depends on the distance from the corresponding point of an object and its brightness. The subsequent simple analysis of a signal with the aid of additional photography of a scene makes it possible to determine the three-dimensional coordinates of the objects in the scene. The spatial resolution of the method is considered.
