OPTICAL IMAGING SYSTEM BASED ON COHERENCE FREQUENCY DOMAIN REFLECTOMETRY

摘要

The present invention relates to an optical imaging system based on a coherence frequency domain echo cytometry, and the objective lens for converting a light source, an electromagnetic wave for outputting a frequency chirp of the electromagnetic wave to spherical wave, a portion of the electromagnetic wave is reflected to form a first beam photodetector portion converts the interference signal of the second beam is interference generated reflected by the first beam and recording the object is reflected by the first reflection means and reflecting means for forming a second beam by transmitting a current signal and , by processing the current signal and a signal processor for generating an image of a photographed object from the interference signal, a current signal is characterized in that the photographed object plane image and a limited amount of the Fresnel zone pattern having the encoded pattern . As a result, not only it can improve the horizontal resolution, but also to overcome the limitations reyirayi. ; Coherence, the chirp of the laser beam, a collimator, a beam splitter, a reference beam lens, objective lens, a condenser, a photodetector, a signal processor
