Title: TWO-DIMENSIONAL SCANNING DEVICE AND LASER RADAR DEVICE WITH TWO-DIMENSIONAL SCANNING DEVICE
Abstract:
Disclosed are a two-dimensional scanning device and a laser radar device with the two-dimensional scanning device. The two-dimensional scanning device comprises a reflector (1), a scanning driving system (2) and an axis (3), wherein the reflector (1) is used to reflect an emergent laser beam (4), a normal line of the reflector (1) forms a fixed included angle α with the axis (3), an incident included angle θ exists between the normal line of the reflector (1) and the incident emergent laser beam (4), the emergent laser beam (4) arrives at a reflector surface of the reflector (1) in a fixed direction, and the scanning driving system (2) drives the reflector (1), through a scanning axis, to rotate 360 degrees around the axis (3), thus the reflection direction of the emergent laser beam (4) then periodically changes, forming an annular laser scanning track, realising two-dimensional scanning for a target.
