A FULLY OR PARTIALLY ELECTRONIC-SCANNED HIGH SPEED 3-DIMENSIONAL LASER SCANNER SYSTEM USING LASER DIODE ARRAYS

摘要

A laser scanner according to the present invention comprises: one or more laser diode (LD) arrays in which a plurality of LDs are placed in a row; a cylindrical rotating drum in which the LD arrays are placed in the longitudinal direction; an operation unit which is placed at the lower part of the rotating drum and rotates the rotating drum by rotating the rotating shaft of the rotating drum; and one or more light receiving units which are placed in the LD arrays and receive reflected light from the light emitted by the LDs. When the operating unit rotates the rotating drum, one LD array among the LD arrays emits light and the receiving units receive reflected light. According to the present invention, the scanning speed, frame rate, and data rate of a laser scanner can be improved, and three-dimensional image information by a laser beam can be easily obtained, thereby facilitating the utilization of three-dimensional imaging technology for various purposes.
