DUAL-DEPTH OPTICAL COHERENCE TOMOGRAPHIC APPARATUS WHICH DUALLY DIVIDES A CONCERN DEPTH DOMAIN

摘要

PURPOSE: A dual-depth optical coherence tomographic apparatus is provided to extend the diameter of light from a reference edge and separate reversely scattered light on the time axis to generate an optical path difference to thereby dually divide a concern depth domain. ;CONSTITUTION: A dual-depth optical coherence tomographic apparatus includes a reference edge(40), a sample shift(50), and standard mirrors(43a,43b). The reference edge comprises a light source generating light, and the standard mirror. The sample shift comprises a galvano mirror. In an optical coherence tomographic apparatus, the two standard mirrors are included in the reference edge.;COPYRIGHT KIPO 2011
