OPTICAL FIBER SCANNING IMAGING DEVICE AND CORRECTION SYSTEM FOR PROJECTION GEOMETRIC DISTORTION OF SAME

摘要

Disclosed are an optical fiber scanning imaging device and a correction system for projection geometric distortion of same. The correction system comprises a test image outputter, an image collector, and a processor, wherein: the test image outputter is used for outputting a predetermined rectangular test image to the optical fiber scanning imaging device; the image collector is used for collecting a projection image output from the optical fiber scanning imaging device; a computer program stored in the processor executes a series of image and signal processing according to data from the test image outputter and the image collector, so as to correct the tilted and distorted projection image as the horizontal rectangular image. The technical problem in the prior art that an XY-type laser scanning imaging device causes a tilted image during projection can be effectively solved.
