AI Technical Summary

Problems solved by technology

[0003] The common method of the existing single-way optical fiber rotary connector is to use optical fiber alignment components to directly couple the optical signal from the rotating mechanism to the stationary mechanism. This coupling method has poor controllability, and there are no other auxiliary coupling or loss compensation devices; these Factors make the rotation and alignment of the optical path extremely difficult, while the performance index of the existing rotary connector is guaranteed by the machining accuracy, the production difficulty is high, and the product production pass rate is low; these factors restrict the development of the rotary signal transmission industry
