Optical fiber array end surface tilt angle measuring instrument and measuring method

Abstract

The invention discloses an optical fiber array end surface tilt angle measuring instrument and an optical fiber array end surface tilt angle measuring method. The optical fiber array end surface tilt angle measuring instrument comprises a helium-neon laser device serving as a light source, a short-focal-length convergent lens, a fixed platform, a long-focal-length convergent lens, a frosted glass plate, a CCD and a computer, wherein the short-focal-length convergent lens is arranged behind the helium-neon laser device, the fixed platform is arranged behind the short-focal-length convergent lens, the long-focal-length convergent lens is arranged behind the fixed platform, the frosted glass plate is arranged behind the long-focal-length convergent lens, the CCD is arranged behind the frosted glass plate, and the computer is connected with the CCD. The optical fiber array end surface tilt angle measuring instrument provided by the invention projects an optical fiber array end surface tilt angle and amplifies a shadow of the end surface tilt angle through a lens group, directly measures the end surface tilt angle by utilizing high-precision angle measuring software, and is simple in structure, simple and convenient to operate, easy to match, low in cost 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...
