Abstract

The invention discloses an imaging system of a fiber fusion splicer and the fiber fusion splicer. An optical micro lens of the imaging system comprises an amplifying lens module formed by combining four curved-surface lenses which include two convex lenses and two concave lenses. One concave lens and one convex lens are connected in a gluing mode to form a glued lens group which is combined with the other convex lens and the other concave lens in sequence. Light emitted by a lighting source projects the axial end face of a fiber onto an imaging chip to achieve imaging through the optical micro lens, and a clear fiber image is provided for self aligning and fiber identification of the fiber fusion splicer. The imaging system enables the working distance of the fiber fusion splicer to reach more than 10mm under the premise that the resolution is ensured. Furthermore, compared with a traditional optical microscope, the conjugate distance of the lens is reduced at least a half and can reach about 65mm, and requirements for miniaturization and portability can be met. Besides, the imaging system is suitable for various kinds of silica fibers.

Description

technical field [0001] The invention relates to optical imaging technology in the field of optical fiber fusion splicing, in particular to an imaging system of an optical fiber fusion splicer and the optical fiber fusion splicer. Background technique [0002] The silica fiber is composed of a silica core and a silica cladding formed around the core, and is wrapped and protected by the coating layer, and light is transmitted in the fiber core. In order to ensure that optical signals can be effectively transmitted over a certain distance in optical fibers, relatively short optical fibers need to be connected together. Optical fiber fusion splicer is a high-precision and practical equipment with a high degree of optical, mechanical and electrical integration. It can provide fast, long-term stable and low-loss optical fiber joints for optical fiber erection and maintenance. The optical imaging system is an important part of the optical fiber fusion splicer. When the optical fib...
