TWO-DIMENSIONAL SCANNING LASER BEAM PROJECTION DEVICE AND LASER RADAR DEVICE

WIPO Patent Application WO/2015/098130

A1

Provided is a two-dimensional scanning type novel laser beam projection device which, in at least one of two perpendicular directions, is capable of variable magnification of the angle of deflection of a laser beam scanned by deflection in two dimensions by a deflection device. This two-dimensional scanning type laser beam projection device projects a two-dimensionally deflected laser beam (SRL), and comprises a laser source (10, 13) which emits the laser beam, a deflection device (14) which deflects in two dimensions the laser beam (LF) emitted from the laser source, and a deflection angle variable magnification element (16) which obtains the deflected laser beam by variably magnifying, in at least one of two perpendicular directions, the deflection angle of the laser beam (LF1) deflection-scanned in two dimensions by the deflection device.
