Abstract

The polar coordinates of an object w.r.t. reference point and also the orientation of the object are measured using an optical goniometer. Such a system enables large tankers to dock at bouy. A tanker(1) approaching floating dock (2) carries photodetectors (5, 6, 7) spaced equally apart. The detectors receive light from a light source (3) turning at a constant predetermined space and from an omni-directional light source (4) whose output is in burst. Angles subtended by the detectors to the beam are determined from time of sweep from one detector to the next. A microprocessor calculates required distance information.
