The compact high-resolution optical fiber imaging system comprises a lighting part and an imaging part, the lighting part adopts a direct structure design, a collimating lens is used for modulating an led light source to obtain parallel light beams in a short optical path, the interference caused by stray light is weakened, and the imaging quality is favorably improved; the imaging part is mainly composed of a microscope objective, a lens cone and a camera,amplification imaging of the to-be-fused optical fiber can be achieved within a short conjugate distance, and pictures are clear. According to the optical fiber imaging system, high image quality isachieved, meanwhile, the size of the fusion splicer can be reduced to a certain degree, and the requirement for portability of the current fusion splicer market is met.

Description

technical field [0001] The invention belongs to the field of optical fiber fusion splicing machines, and in particular relates to a compact high-resolution optical fiber imaging system. Background technique [0002] In today's information age, with the rapid development of the Internet of Things, optical fiber communication has become the main force of information transmission. The popularization of wired optical networks requires a large number of optical fiber connections. As the leading instrument (equipment) for optical fiber connection, optical fiber fusion splicers are responsible for important role. [0003] The key performance index of the optical fiber fusion splicer is the optical power loss of the fusion splicing point. Only a high-quality fusion splicing point can ensure the long-distance transmission of optical signals. To ensure the quality of fusion splicing, it is necessary to complete the physical core of the optical fiber at both ends. Accurate docking , w...

[0004] The published invention patent CN 107121727A proposes a fiber core identification imaging system. The illumination part adopts the collimation reflection type, which increases the light loss and needs to increase the positioning space of the lighting lamp in the fuselage. The imaging part has small magnification and poor resolution of the lens. The high restrictive factors cannot meet the needs of today's market for small and exquisite optical fiber imaging systems of fusion splicing machines and clear pictures.

The published invention patent CN102998788A proposes an imaging system for an optical fiber fusion splicer, which has a large magnification, but the conjugate distance is large, which increases the assembly space of the rack, and at the same time, the imaging resolution is low, which affects the judgment of the fiber core by the software and the customer's visual perception of the image
