Optical imaging system based on coherence frequency domain reflectometry

摘要

Provided is an optical imaging system based on a coherence frequency domain reflectometry, including: a light source generating an electromagnetic wave; a splitting unit splitting the electromagnetic wave into first and second beams; a reflecting unit reflecting the first beam and re-transmitting the reflected first beam to the splitter; an objective lens projecting the second beam onto an object to be recorded; a photodetector transforming an interference pattern into a current signal, wherein the first beam reflected from the reflector interferes with the second beam reflected from the object to generate the interference pattern; and an electronic processing unit processing the current signal to generate an image of the object from the interference pattern. Therefore, a lateral resolution can be improved, and Rayleigh limits can be overcome.
