Abstract

The invention discloses an optical fiber scanner connecting structure. The optical fiber scanner connecting structure comprises a first scanning driver provided with a fixed end and a free end; a connecting base provided with a first groove body, in which the fixed end of the first scanning driver is arranged; and at least one first pressing piece arranged on the side wall of the first groove body, wherein the tail end of the first pressing piece extends into the first groove body and presses the fixed end of the first scanning driver. The scanning beam emitting end of an optical fiber performs one-dimensional vibration or two-dimensional vibration under the driving of the first scanning driver. The scanning driver is tightly pressed in the groove body through the pressing piece, and the scanner is fixed. The optical fiber is fixedly arranged on the first scanning driver. The use of the connecting part is avoided, the loss of the force due to the connecting part is avoided. The drivingforce of the first scanning driver can be effectively transmitted to the optical fiber without being attenuated, and therefore the vibration amplitude of the optical fiber is increased.

Description

technical field [0001] The invention relates to the technical field of optical fiber scanning devices, in particular to a connection structure of an optical fiber scanner. Background technique [0002] Conventional fiber optic scanners use piezoelectric elements to vibrate an optical fiber at high speed to emit illumination light, thereby scanning the illumination light on the subject. [0003] Existing piezoelectric elements or tubular piezoelectric elements (PZT tubes), four electrodes arranged in the circumferential direction at equal intervals on the surface of the PZT tubes, and optical fibers inserted into the PZT tubes are passed through the connecting member And the end part of the optical fiber was fixed on the PZT tube. When the PZT tube is bent and deformed, a force in the vertical direction acts on the optical fiber via the connecting member, and the optical fiber is subjected to bending vibration due to this force. Furthermore, by synthesizing the bending vibr...
