DEVICE OF OPTICAL COHERENCE TOMOGRAPHY

摘要

PURPOSE: An optical coherence tomography device is provided to accurately sense interference fringes generated from light sources in different bands without signal interference by including an optical fiber bragg grating. CONSTITUTION: A light source includes a first light source(11) and a second light source(12). A first interferometer includes a first reference end(R1). The first reference end includes a collimator(41a) converting a first reference light(93) into a parallel light, and a reference mirror(42a) reflecting the first reference light. A second interferometer includes a second reference end(R2). The second reference end includes a collimator(41b) converting a second reference light(94) into a parallel light, and a reference mirror(42b) reflecting the second reference light.
