Abstract

The invention discloses a space optic coupling detection device based on optical fiber arrays. The device comprises a plurality of multimode optic fibers. The multimode optic fibers are provided with two end faces. Bare optic fiber end faces are arranged at one ends of the multimode optic fibers, and self-focusing lenses are arranged at the other ends. The bare optic fiber end faces of the plurality of multimode optic fibers are in connected tightly, and the self-focusing lenses are arranged in micro lenses in a matching mode. By means of the space optic coupling detection device, the problems of reduction of coupling efficiency and interruption of signals caused by facula shaking, damaging and drifting can be solved.

Description

technical field [0001] The invention relates to the field of electronic information, in particular to a spatial optical coupling detection device based on an optical fiber array. Background technique [0002] Wireless laser communication (Free Space Optic, FSO) is a communication method with great development prospects. Because it uses an open atmospheric channel as a propagation medium, the atmospheric environment will have a greater impact on the signal, and this impact will vary with changes in weather and seasons. During long-distance communication, atmospheric turbulence, scattering, and various meteorological conditions (such as wind, rain, fog, haze, etc.) will cause the energy of the spot to attenuate, the shape of the spot will be damaged to varying degrees, and flicker, shake, and drift . This brings great difficulties to signal reception and detection, especially the jitter of the light spot. The randomness of signal optical jitter will not only bring detection...
