Abstract
The present disclosure provides a full-field OCT system using a wavelength-tunable laser, which can observe peaks of a short-time A-line profile corresponding to each time point at which interference images of an object to be measured are acquired, so as to measure a depth direction movement of the object to be measured, and can correct the phases of interference signals on the basis of the measured depth direction movement, so as to generate an OCT image which is compensated for the depth direction movement.
