Abstract
An object information processing apparatus includes a focussing unit for focussing light information from an object point; a light transmission unit for transmitting the light information from the object point to the focussing unit via first and second optical passages; and mask units provided respectively in the first and second optical passages in the light transmission unit and formed respectively with predetermined patternings which are in negative and positive relation to each other. By virture of the mask units, the light information from the object point is blocked into a plurality of distance informations from which distance patterns are obtained. The apparatus can recognize an object in three dimensions using the distance patterns. Since the apparatus has no mechanically movable parts and the light passed through the first and second optical passages is focussed side by side on a photosensor, a high resolution is obtained and mutual references of corresponding points of the object are readily obtained.
