Abstract

The invention belongs to the technical field of optical fibers, and discloses an optical fiber parameter measuring system and method. A to-be-measured optical fiber is fixed in an optical fiber clamp,the optical fiber clamp is fixed on a two-dimensional motorized goniometers stage, and a camera is fixed on a three-dimensional electric translation stage; laser is generated by adopting a laser light source, after passing through the to-be-measured optical fiber, the laser is irradiated on an area array sensor of the camera to form a light spot, and the camera transmits light spot image information collected in real time to an upper computer; an optical fiber collimation controller and the upper computer cooperatively control the movement of the two-dimensional electric motorized goniometersstage and the three-dimensional electric translation stage, so that an emergent light beam of the to-be-measured optical fiber and the area array sensor of the camera are perpendicular to each other;and the upper computer performs calculation according to the collimated light spot image information to obtain optical fiber parameters. According to the system and the method, the parameters of themonomode optical fiber can be measured.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a system and method for measuring optical fiber parameters. Background technique [0002] Optical fiber not only promotes the development of communication and informatization, but also has a wide range of applications in science, industry and medicine. Due to its advantages in long-distance transmission, single-mode fiber has more and more application scenarios. For example, in medical applications, the lighting system used in advanced surgical microscopes is designed by taking advantage of some characteristics of optical fibers. When performing ENT or narrow abdominal surgery, ordinary lighting cannot meet the surgical lighting requirements. Generally, the lighting methods used are coaxial lighting and oblique lighting. The angle of oblique lighting is calculated according to the divergence angle and off-axis degree of the optical fiber. The special light source is real...
