Abstract

PURPOSE:At one point, the transmitter is provided which sweeps the fixed space horixontally and vertically leaving no space by laser rays of a narrow beam width, and at the other, the receiver is provided which sweeps the space above oppositely, thereby detecting each other surely within the region of a long distance of approxiamately 100km if two points where the trasmitter and the receiver are provided afford a view of each othre.
