Optical functional surface and laser radar outer cove using the same

Abstract

The invention provides an optical functional surface comprising an inner reinforcing film, an outer reinforcing film, a waterproof film and an anti-reflection film. The inner reinforcing film is disposed on the inner side of a cover body; the outer reinforcing film is disposed at the outer side of the cover body; and the waterproof film and the anti-reflection film are pasted on the outer reinforcing film successively. The optical functional surface has advantages of simple structure, low cost and high penetration property and the receiving efficiency of the laser radar detector is ensured.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to an optical functional surface and a lidar cover using the optical functional surface. Background technique [0002] Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of targets. It is an active remote sensing device that uses a laser as a source of emission and uses photoelectric detection technology. Lidar is an advanced detection method combining laser technology and modern photoelectric detection technology. It is composed of transmitting system, receiving system, information processing and other parts, and is widely used in industries, intelligent robots, automobiles and other fields. [0003] Therefore, LiDAR has the characteristics of small size, high resolution, and strong anti-interference ability. The stable and reliable operation of these characteristics is inseparable from the LiDAR housing, an importan...

AI Technical Summary

Problems solved by technology

There is a problem of astigmatism, which makes the image spot bigger and affects the receiving efficiency of the detector in the lidar system

On the other hand, most lidar covers currently on the market are designed in a cylindrical shape. The specific structure is that the inner diameter of the bottom is smaller than the inner diameter of the top, the outer diameter of the bottom is smaller than the outer diameter of the top, and the inner and outer sides are made of unequal wall thickness and specific curvature. Curve; although it can achieve the relevant penetrating function, but due to the relatively simple structure, it is not flexible enough, which affects the overall appearance of the lidar system, and cannot meet the design and aesthetic needs of different customers.
