Optical fiber structure and optical fiber scanner

Abstract

The invention discloses an optical fiber structure and an optical fiber scanner adopting the optical fiber structure, the optical fiber structure comprises a fixed part and a cantilever part, the fixed part is used for being fixed on an actuator of the optical fiber scanner, and the cantilever part exceeds the actuator to form an optical fiber cantilever; the cantilever part comprises a buffer part and a main cantilever section, the buffer part is located between the main cantilever section and the fixed part, the optical fiber shape of the buffer part and the front and rear optical fibers form a shape difference, and the buffer part comprises one or more buffer sections. The stress borne by the fixed part when the optical fiber cantilever swings can be effectively reduced.

technical field

[0001] The invention relates to the field of display technology, in particular to an optical fiber structure and an optical fiber scanner using the optical fiber structure. Background technique

[0002] Optical fiber is an important optical waveguide device. Using optical fiber to guide the light emitted by the light source or collecting image information at the end of the optical fiber is two important aspects of optical fiber applications, such as medical endoscope systems and laser projection systems. It is an important breakthrough in the application of optical fiber to realize the vibration scanning of optical fiber by integrating optical fiber with piezoelectric devices with vibration characteristics. So far, many optical fiber scanning systems based on this concept have emerged on the market. At present, optical fiber-based scanning devices are mostly prepared by binding controllable vibration devices and optical fibers, such as piezoelectric ceramic ...
