Document Type and Number:
Japanese Patent JP6535985
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To quickly acquire a functional OCT image.SOLUTION: An optical coherence tomography device for acquiring tomographic image data on a specimen by processing an OCT signal with measurement light and reference light irradiated to the specimen includes acquisition means for acquiring a plurality of OCT signals that are temporally different about the same position on the specimen, and calculation processing means for processing the plurality of OCT signals acquired by the acquisition means to acquire motion contrast data on the specimen. The acquisition means acquires a plurality of OCT signals at a second position different from a first position on the specimen after acquiring a plurality of OCT signals at the first position, and the calculation processing means processes the plurality of OCT signals acquired at the first position to acquire motion contrast data at the first position while the acquisition means acquires a plurality of OCT signals at least at one of the first position and the second position.
