Optical fiber bundle fine adjustment device

Abstract

An optical fiber bundle fine adjustment mechanism comprises an optical fiber bundle, an X / Z system plane adjustment mechanism, a Y-axis movement mechanism and a Z-axis rotation adjustment mechanism. Wherein the optical fiber bundle is combined with the X / Z system plane adjusting mechanism through the connecting mechanism to form a structure capable of enabling the optical fiber bundle to perform micro translation in the X-axis direction and the Z-axis direction; the Y-axis moving mechanism consists of a front moving bottom plate and a rear moving bottom plate which are connected in series from front to back; meanwhile, the X / Z system plane adjusting mechanism combined with the optical fiber bundle is seated in a rotary circular groove formed in the front part of the front moving bottom plate through a rotary positioning table in a Z-axis rotary adjusting mechanism connected with the lower part of the X / Z system plane adjusting mechanism, so that the Z-axis rotary adjusting mechanism capable of enabling the optical fiber bundle to horizontally deflect is formed; therefore, the optical fiber bundle fine adjustment mechanism capable of performing fine adjustment on the optical fiber bundle in the X, Y and Z directions is formed.

Description

Technical field: [0001] The invention relates to an optical fiber bundle fine-tuning device, in particular to a mechanism for adjusting light reception and transmission, and belongs to the technical field of optical calibration equipment and biological optics applications. Background technique: [0002] At present, most of the optical fiber bundles used in light receiving and transmission in the market are fixed, and it is impossible to flexibly calibrate the center position of the optical fiber bundle according to the offset of the center position of the incident light source; especially in the field of biomedicine, large Most of them use optical fiber to transmit the signal of the incident light source, but the center of the incident light source has a certain offset. However, the fixed fiber bundle cannot be flexibly adjusted to the center position, and the fine-tuning and calibration of the light spot cannot be realized. [0003] Therefore, designing a mechanism capable ...
