AI Technical Summary

Technical Problem

The anti-interference capability of the optomechanical system needs to be improved. Stray light seriously interferes with the emitted and echo signals, resulting in a decrease in signal quality.

Method used

An optomechanical system was designed, which forms a transmit optical channel and an echo optical channel on an isolator. The isolator partially or completely separates the transmit optical channel from the echo optical channel, reducing stray light interference. The corresponding arrangement of the optical scanning element and the optical receiving component ensures that the optical signal is transmitted in their respective channels.

Benefits of technology

It effectively reduces stray light interference with optical signals, enhances the independence and signal quality of the optomechanical system, improves ranging capability and detection field of view, and meets the requirements of high-precision imaging.

Abstract

The embodiment of the application discloses an optical mechanical system, which comprises a shell, a light emitting assembly, a light receiving assembly, a light scanning assembly and a spacer. The spacer is formed with a transmitting light channel and a return light channel. The light emitting assembly is arranged corresponding to the first light inlet of the transmitting light channel. The first light scanning element is arranged corresponding to the first light outlet of the transmitting light channel. The first light scanning element is also arranged corresponding to the second light inlet of the return light channel. The light receiving assembly is arranged corresponding to the second light outlet of the return light channel. At least part of the transmitting light channel is separated from at least part of the return light channel. The optical mechanical system of the embodiment of the application can reduce or even avoid the interference of stray light on the transmitting light signal and the return light signal. Meanwhile, at least part of the transmitting light channel is separated from at least part of the return light channel, which can improve the independence of the transmitting light channel and the return light channel and reduce the crosstalk between the transmitting light signal and the receiving light signal.
