Main mirror of high-lidar fastening

The fastening construction of the main mirror of a high lidar is presented in this paper. Lidar is light radar that consists of the light emission source and receiver of the reflected light signal. Lidar design is as done as follows. Optical axes of the receiver and light emission source don´t change position relative to the motionless base because it is worthwhile to simplify the main mirror fastening construction. Three supports regulated on height are placed on the base. These supports are situated on tops of the equal sides of the triangle. Unloading is made on six points, each one of the support holds equal arm level. Balls are placed on the end of the levels in the slots. Small thickness ring with small rigidity is placed on the balls. A rubber laying downward to sideward is glued on the back side of the ring. While putting the mirror on the supports system, the leveling of the load from the mass on the backside of the mirror surface is also done. Radial fastening and unload make as followers: the cut ring is based on the mirror through rubbery laying of screws moved in pillar slots after mirror adjustment. The height of the crimped lock relative to the mirror face must provide radial mirror unloading. Suggested construction allows reducing labour content of manufacturing and assembly.
