Abstract
A laser-optical position detecting module with a laser as a light source is disclosed, which includes a laser mode conversing assembly, having a laser source capable of emitting a time-modulated laser beam; a laser mode conversing unit, used to expand the time-modulated laser beam to a two-dimension sensing plane; a drive control unit, adopted for driving the laser source to emit the time-modulated laser beam; and a detector matrix. The laser mode conversing unit has a phase delay device and a passive optical device capable of reflecting the light; so that, through the laser mode conversing unit, the laser-optical position detecting module can expand the light emitted by the laser source to the two-dimension sensing plane without using any other mechanical scanning.
