POLARIZATION-SENSITIVE FULL-FIELD OPTICAL COHERENCE TOMOGRAPHY SYSTEM, AND CONTROL SYSTEM AND CONTROL METHOD THEREOF

摘要

A polarization-sensitive full-field optical coherence tomography system according to the present invention may include: a light source unit for emitting light; a beam splitter that separates the light emitted from the light source unit, emits the light to a sample side and a reference side, and enables the light that has been reflected from the reference side and the sample side to be incident; an imaging unit for acquiring the image of an interference light reflected from the beam splitter; a linear polarizer for linearly polarizing the light of the light source unit; a quarter-wave plate for converting the linearly polarized light passed through the linear polarizer into an elliptically polarized light and then for providing the converted light to the sample side and the reference side; and a selected polarized light transmission device for, provided in the imaging unit, temporally selecting and passing a horizontal component and a vertical component of the polarized light, wherein the imaging unit has a single camera. The present invention can achieve advantages of eliminating an inconvenience of matching error alignment between image pixels, an inconvenience of pixel response rate correction of a camera, and an inconvenience of a strict adjustment of optical alignment, and significantly reducing the unit price of a product and reducing the size of a system.
