OPTICAL COHERENCE TOMOGRAPHY

摘要

According to an embodiment of the present invention, an apparatus for optical coherence tomography comprises a light source for generating a sample beam which is incident to an object and a reference beam which causes interference with the sample beam. The apparatus for optical coherence tomography generates an interference image formed by interference between the sample beam and reference beam, and photographs an image of an object within a medium. The apparatus for optical coherence tomography further comprises: a spatial light modulator (SLM) to which a plurality of lamp patterns are applied to adjust an incident angle of the sample beam; and a diffraction grating (DG) which is configured to project only a first diffraction component of the reference beam.
