| 摘要 |
An optical coherence tomography (OCT) apparatus is disclosed. The apparatus of the present invention comprises: an optical fiber coupler light respectively diverging incident light from a light source to a mirror and a sample; a first path change unit changing length of a path of incident light on the sample; a second path change unit changing optical path length applied to the mirror; a control unit controlling the second path change unit for optical path length changed by the first path change unit and optical path length changed by the second path change unit to maintain a constant difference based on the optical path length of the first path change unit. [Reference numerals] (22,32) Optical system; (23,33) Path change unit; (34) Sample; (40) Control unit |
