Abstract
An optical coherence tomographic device configured to acquire a tomographic image of a subject by using an optical interferometry is provided. The optical coherence tomographic device include: a detector configured to detect interference light acquired by the optical interferometry, and to output an interference signal of the interference light; and a processor configured to calculate von Neumann entropy of noise components by using the noise components and signal intensities of the interference signals corresponding to at least one interference light detected by the detector.
