Description

Technical Field

[0001] This utility model relates to the field of wireless laser communication technology, specifically to an integrated automated testing platform for the optical performance of wireless laser communication. Background Technology

[0002] Wireless laser communication technology is a wireless communication technology that uses a laser beam as a carrier to achieve high-speed data transmission in free space. It does not require physical media such as optical fibers and has the characteristics of large bandwidth, high speed, strong resistance to electromagnetic interference, and good confidentiality. It is often used for long-distance communication between satellites and between ground and spacecraft. It can also be used to build temporary high-speed communication links between high-rise buildings in cities. However, due to factors such as atmospheric attenuation and obstruction, the transmission stability is easily affected by the environment.

[0003] An automated optical performance testing platform is a specialized device that integrates optical sensing, data acquisition, and intelligent control modules. It can automatically complete parameter testing of optical components or systems, covering indicators such as transmittance, refractive index, wavelength accuracy, and polarization state. It replaces manual operation, improves testing efficiency and data consistency, and is suitable for batch quality inspection of products such as lenses, fiber optic devices, and laser modules. It is widely used in optoelectronic manufacturing, communication equipment research and development, and other fields.

The outer wall of the rotary motor is fixedly connected with uniformly distributed heat dissipation fins.

[0019] By adopting the above technical solution, the heat dissipation fins serve to dissipate heat from the rotating motor.
