Optical fiber connector end face parameter measuring device and measuring method

Abstract

In order to solve the technical problems that the existing optical fiber connector end face parameter measurement method is susceptible to the environmental influence, the test accuracy is, the measurement efficiency is low and the dynamic range is small, the invention provides an optical fiber connector end face parameter measurement device and measurement method. The measurement device comprises a light source, a convergent mirror, a target plate, a collimating mirror, a first beam splitter and an absorber, which are arranged in sequence along the same light path; one surface of the first beam splitter facing to the collimating mirror is defined as a first mirror surface, and a first microobjective is arranged on a reflection light path of an outgoing beam of the collimating mirror after being reflected by the first mirror surface; a second beam splitter, a beam expansion system and a Shaker-Hartmann wavefront sensor are arranged on a transmission light path of the outgoing beam ofthe first microobjective after being transmitted by the first mirror surface in sequence; a second microobjective and an imaging detector are arranged on the reflection light path of the second beam splitter in sequence; and the imaging detector arranged on a one-dimensional electronic control translation platform, and the one-dimensional electronic control translation platform is connected with acontrol and data analysis computer via a driver.

Description

technical field [0001] The invention belongs to the field of optics, and relates to a measuring device and a measuring method for an end face parameter of an optical fiber connector. The parameters of the end face of the optical fiber connector include the three-dimensional shape of the end face of the optical fiber connector, the radius of curvature, the grinding eccentricity and the height of the optical fiber. Background technique [0002] The function of the fiber optic connector is to connect the fibers so that the optical signal can be transmitted in the fiber optic system with the lowest loss. It is an important component of the fiber optic communication system. In order to minimize the impact of optical fiber connectors on the system when intervening in optical communication lines, its optical performance must be guaranteed, and the factor to measure the optical performance of optical fiber connectors is not external reasons, but the quality of its own end face. The...
