Abstract

The invention relates to a self-adaptation optical fiber collimator based on a flexible hinge. The self-adaptation optical fiber collimator is characterized in that a connectable optical fiber end cap is fixed on an end cap holder which is connected to a collimator base by using the flexible hinge; one end of a piezoelectric ceramic is clung to the end cap holder, the other end of the piezoelectric ceramic is connected to the collimator base, and finally an output end of the optical fiber end cap is placed in a focal position of a collimating lens. The self-adaptation optical fiber collimator has the advantage that the rapid high-accuracy control on fiber laser inclined aberration is realized by changing a piezoelectric ceramic driving voltage under the inverse piezoelectric effect of the piezoelectric ceramic.

Description

Technical field [0001] The invention relates to an optical fiber collimator structure, in particular to an adaptive optical fiber collimator based on a flexible hinge. Background technique [0002] The tilt control of the beam is very important for stabilizing the axial position of the beam, and is of great significance in astronomical observation, laser communication, lidar, photoelectric tracking, and coherent combination of array beams. Especially in the fiber laser array beam synthesis system, multi-beam co-target aiming can be realized by controlling the tilt of the fiber exiting beam. Co-targeting plays an important role in controlling the coherence of fiber laser array beams. In the corresponding optical system, a device that can control the beam to produce rapid and small angle changes is required. The traditional method of correcting beam tilt is to use a high-speed tilt mirror and an adaptive fiber source collimator (AFOC). The mechanical resonance frequency of the h...
