Problems solved by technology
[0003] Existing lidar mostly uses double-sided mirrors as reflectors. The angle between the two reflective surfaces of this reflector is determined during production and processing, and the angle between the two reflective surfaces cannot be adjusted according to requirements.
Also, double sided mirrors are usually more expensive than two single sided mirrors

The invention discloses a scanning mirror assembly and a laser radar, the scanning mirror assembly comprises a scanning mirror, the scanning mirror comprises a first single-sided mirror and a second single-sided mirror, the first single-sided mirror and the second single-sided mirror each comprise a reflecting surface and a back surface which are oppositely arranged, the first single-sided mirror and the second single-sided mirror are stacked into a whole, the back surface of the first single-sided mirror faces the back surface of the second single-sided mirror; an adjusting assembly which comprises a telescopic piece and a pressing block which is eccentrically arranged, wherein the telescopic piece is arranged between the first single-sided mirror and the second single-sided mirror, and is respectively propped against the back surfaces of the first single-sided mirror and the second single-sided mirror; the pressing block abuts against the first single-face mirror or the second single-face mirror, and the pressing block can be operated to compress or release the telescopic piece. In this way, the included angle between the two reflecting surfaces of the scanning mirror can be adjusted.
Description
technical field [0001] The present application relates to the technical field of radar, in particular to a scanning mirror assembly and a laser radar. Background technique [0002] The laser radar hits the object with the beam emitted by its laser emitting component to cause light scattering, and part of the beam forms a receiving beam and is received by the receiving component of the laser radar. At this time, according to the principle of laser ranging, the distance from the laser radar to the object can be obtained. distance. [0003] Existing lidars mostly use double-sided mirrors as reflectors. The angle between the two reflective surfaces of this reflector is determined during production and processing, and the angle between the two reflective surfaces cannot be adjusted according to requirements. In addition, the cost of double-sided mirrors is usually higher than that of two single-sided mirrors. Contents of the invention [0004] The technical problem mainly sol...
