TWO-DIMENSIONAL SCANNING LASER BEAM PROJECTION DEVICE AND TWO-DIMENSIONAL DISTANCE-MEASURING EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To achieve a new two-dimensional scanning laser beam projection device that has a large deflection angle.SOLUTION: There is provided a two-dimensional scanning laser beam projection device that emits a two-dimensionally deflected laser beam, the device including laser light sources 10 and 12 that emit laser beams, a deflector 16 that two-dimensionally deflects and scans the laser beam LF emitted from the laser light sources, and a deflection lens element 18 that extends the deflection angle of the laser beam LD, which has been two-dimensionally deflected and scanned by the deflector, in at least one of two directions orthogonal to each other.
