Optical fiber deviation corrector

Abstract

The invention discloses an optical fiber deviation corrector. The optical fiber deviation corrector comprises a parallel light emitter and a parallel light receiving detector. The parallel light emitter comprises a laser emitter, an angle modulation device, a parallel light control lens component and a light spot limiting diaphragm. The parallel light receiving detector comprises an optical fiber pixel point integration plate, transmission optical fibers, a photoelectrical converter and a signal acquiring and processing device. The angle modulation device modulates a laser beam into preset-angle divergent light, the parallel light control lens component modulates the divergent light into parallel light, the light spot limiting diaphragm modulates the parallel light into parallel light spots as large as the optical fiber pixel point integration plate, the parallel light spots is emitted to the optical fiber pixel point integration plate and acquired by the same to obtain optical signals, the optical signals are transmitted to the photoelectrical converter through the transmission optical fibers and converted into electrical signals by the photoelectrical converter, and the electrical signals are transmitted to the signal acquiring and processing device. The optical fiber deviation corrector has advantages that light energy is saved, detection accuracy is improved, and minor deviation or defect sizes of parts can be calculated accurately.

Description

technical field [0001] The invention belongs to the technical field of optical devices, in particular to an optical fiber deviation corrector. Background technique [0002] In the prior art, when the optical rectifier is working, the monochromatic laser light source of the optical rectifier emits a laser beam to the parallel light control lens, but when emitting the laser beam, because the divergence angle of the laser beam is not limited, the laser beam will form a The area of ​​the light field is larger than the area of ​​the parallel light control lens, resulting in a waste of light energy. In addition, when testing the parts to be tested, the accuracy of the optical rectifier is limited by the size and spacing of the photoelectric conversion units on the photoelectric converter. The precision is limited, and it is impossible to accurately calculate the small movement of the part, the offset, or the size of the defect. [0003] Therefore, in the prior art, there is an op...
