Abstract
An optical coherence tomographic device may include: a light source; a measurement light generator that generates measurement light and generates reflected light from a target region in a scattering sample by irradiating the target region with the measurement light; a reference light generator that generates reference light; an interference light generator that generates interference light by combining the reflected light and the reference light; an interference light detector that detects the interference light and generates interference signals by converting the interference light; and a processor. The processor may cause the OCT device to execute: acquiring tomographic images for a same cross section in the target region in time series from the interference signals; calculating an entropy of the generated interference signals based on the tomographic images; and specifying a dynamic part in the tomographic images based on the calculated entropy.
