Abstract

The invention discloses a spatial light-optical fiber coupling device and method based on visual detection. The device comprises an imaging module and an imaging adjustment module, the imaging module is used for carrying out coupling imaging on the spatial light emitted by the spatial light emitting device to obtain a first imaging picture and transmitting the coupled spatial light to the imaging adjustment module, and the imaging adjustment module is used for generating a second imaging picture after obtaining the first imaging picture and carrying out position adjustment on the second imaging picture to generate a third imaging picture; meanwhile, the adjustment parameters are obtained and then sent to the imaging module, and the imaging module is further used for conducting imaging adjustment on the first imaging picture according to the adjustment parameters. After the first imaging picture is obtained through the imaging adjustment module, the second imaging picture is generated, and the second imaging picture is adjusted to obtain the adjustment parameter, so that the imaging module performs imaging adjustment on the first imaging picture according to the adjustment parameter, the maximum coupling light power can be obtained when the spatial light is coupled to the optical fiber, and the optical fiber coupling efficiency is 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...
