Problems solved by technology
At present, the fixing methods of optical fibers are mostly glued or welded, that is, the optical fiber is glued or welded to the outer surface or inner hole of the piezoelectric material tube, but because the piezoelectric material tube itself vibrates through stretching and deformation, this makes the optical fiber and The connection between piezoelectric material tubes is prone to fatigue and looseness, and the stability and service life are difficult to meet the requirements of use

The invention discloses an optical fiber scanner. The optical fiber scanner comprises a first piezoelectric material tube actuator, an end sleeve and an optical fiber; the two axial ends of the firstpiezoelectric material tube actuator are a fixed end and a free end correspondingly, the end sleeve is fixedly arranged at the free end of the first piezoelectric material tube actuator, and the end sleeve is provided with an optical fiber mounting hole penetrating through the end sleeve; and the optical fiber is arranged in the first piezoelectric material tube actuator in a penetrating mode, theend of the optical fiber penetrates out of the optical fiber mounting hole of the end sleeve, the part, penetrating out of the optical fiber mounting hole, of the optical fiber forms an optical fibercantilever, and the part, close to the optical fiber cantilever, of the optical fiber is fixedly connected with the optical fiber mounting hole. By adopting the structure that the end sleeve is fixedly connected with the piezoelectric material tube actuator and the optical fiber is connected with the end sleeve, it is ensured that an optical fiber connecting structure is not influenced by deformation of the piezoelectric material tube actuator, the stability of the connecting part is guaranteed, the service life is long, and fixation is firm.
Description
technical field [0001] The invention relates to the technical field of optical fiber scanning, in particular to an optical fiber scanner. Background technique [0002] The piezoelectric material tube actuator is generally a dichotomous tube electrode actuator or a quadruple tube electrode actuator. The piezoelectric material tube actuator includes a piezoelectric material tube. The outer surface of the piezoelectric material tube is provided with a pair or two pairs of The axis of the piezoelectric material tube is symmetrical to the outer electrode, and the inner surface of the piezoelectric material tube is provided with an inner electrode matched with the outer electrode. The part of the piezoelectric material tube located between the outer electrode and the corresponding inner electrode is radially polarized, so that when the inner electrode and the outer electrode are connected to an external driving device, the free end of the piezoelectric actuator moves along its cor...
