Abstract

The invention discloses a spatial light-fiber coupling device and method based on visual detection, the device includes: an imaging module and an imaging adjustment module; the imaging module is used to couple and image the spatial light emitted by a spatial light emitting device to obtain the first An imaging map, and used to transmit the coupled spatial light to the imaging adjustment module, the imaging adjustment module is used to obtain the first imaging map to generate a second imaging map, and adjust the position of the second imaging map to generate a third imaging At the same time, the adjustment parameters are obtained and sent to the imaging module, and the imaging module is also used to perform imaging adjustment on the first imaging image according to the adjustment parameters. After the first imaging image is obtained by the imaging adjustment module, the second imaging image is generated, and the adjustment parameters are obtained by adjusting the second imaging image, so that the imaging module can perform imaging adjustment on the first imaging image according to the adjustment parameters, and can couple the space light to the optical fiber The maximum coupling optical power can be obtained at this time, and the efficiency of fiber coupling can be automatically adjusted.

Description

technical field [0001] The invention relates to the technical field of space laser communication, in particular to a space light-fiber coupling device and method based on vision detection. Background technique [0002] Compared with microwave communication, laser communication has extremely high potential communication data rate (greater than tens of gigabits per second or even higher), and the size, quality and power consumption of communication terminals are small. In China, a large number of universities and research institutes have developed Research on laser communication technologies such as satellite-ground, inter-satellite, and free space. Space light-single-mode fiber coupling technology is one of the key technologies in space laser communication, and its coupling efficiency seriously affects the quality of laser communication. [0003] In the real scene, when the space laser is transmitted to the communication terminal through the space channel, the beam spot diame...
