Abstract

The invention discloses an optical-fiber scanning imaging system and optical-fiber scanning imaging equipment. The optical-fiber scanning imaging system includes an optical source, scanning optical-fiber, a control circuit, a collimating microlens array and an angle expanding lens group. Optical beams exiting the optical source are coupled into the scanning optical-fiber, then exits from the scanning optical-fiber, then is collimated by the collimating microlens array, then passes through the angle expanding lens group, and then exits. A technical scheme of collimating, through the collimatingmicrolens array, the optical beams exiting from the scanning optical-fiber is employed, thus collimation of the optical beams exiting from all collimating microlenses in the collimating microlens array is ensured, resolution of images formed by scanning of the optical-fiber scanning imaging system is also ensured, thus a display effect of the images formed by scanning is ensured, and cases wherethe optical beams exiting from the scanning optical-fiber becomes thicker with distance increasing, and thus the display effect of the images formed by scanning is impacted are avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an optical fiber scanning imaging system and optical fiber scanning imaging equipment. Background technique [0002] Optical fiber scanning technology is one of the future development trends of scanning display technology due to its strong color performance, high brightness, long life, small size, light weight and low power consumption. [0003] When scanning through the optical fiber, according to the different numerical apertures of the optical fiber, there are different degrees of divergence in the light emitted from the optical fiber, but the light will become thicker with the increase of the outgoing distance. Larger light spots will be formed on the projection surface such as the wall, which will affect the resolution and screen size of the image formed by scanning, thereby affecting the display effect of the image formed by scanning. [0004] Please refer to figure 1...
