An optical fiber array end face inclination angle measuring instrument and measuring method

Abstract

The invention discloses an optical fiber array end face inclination angle measuring instrument and a measuring method thereof. The optical fiber array end face inclination angle measuring instrument comprises a helium-neon laser as a light source, a short focal length converging lens located behind the helium-neon laser, a short focal length converging lens located A fixed platform at the rear, a long focal length converging lens located behind the fixed platform, a ground glass sheet located behind the long focal length converging lens, a CCD located behind the ground glass sheet and a computer connected to the CCD. The optical fiber array end face inclination angle measuring instrument of the present invention utilizes the projection of the end face inclination angle of the optical fiber array, amplifies the end face inclination angle shadow through the lens group, and uses high-precision angle measurement software to directly measure the end face inclination angle. The structure is simple, It is easy to operate, easy to match, low in price, and high in measurement accuracy.

Description

technical field [0001] The invention belongs to the field of measuring devices, and in particular relates to a measuring instrument and a measuring method for the inclination angle of an optical fiber array end face. Background technique [0002] At present, the methods for measuring angles at home and abroad are mainly divided into: mechanical goniometric method, electromagnetic goniometric method, optical goniometric method and so on. [0003] The mechanical angle measurement method is the earliest angle measurement technology. The main representative instrument is the multi-tooth indexing table, which has the advantages of precision and convenient operation, and has been widely used in the machinery manufacturing industry. Manual rotation is mostly used, the efficiency of angle measurement is low, manual intervention is required, and the structure is complex and bulky, which is inconvenient for measuring the angle of a small object such as an optical fiber array; the elec...
