Laser radar optical axis adjustment device

The invention relates to a laser radar technology, in particular to a laser radar optical axis adjustment device. The laser radar optical axis adjustment device disclosed in the invention comprises acollimating mirror, a mirror base, and a double-optical-wedge adjustment group, wherein the collimating mirror and the double-optical-wedge adjustment group are connected with the mirror base separately; the double-optical-wedge adjustment group comprises two optical wedges, two optical wedge bases and two lens cones; the two optical wedges are mounted on the two optical wedge bases respectively;the two optical wedge bases are arranged in the two lens cones respectively; the contact surfaces between the optical wedge bases and the lens cones are stepped surfaces; the optical wedge bases are in tight sliding fit with the steps of the lens cones, and the optical wedge bases rotate around the optical axis in the lens cones; and the two lens cones are connected back and forth and fixed on themirror base.
