Abstract: An optical tomography apparatus has a measurement unit that divides light output from a light source into measurement light and reference light, that repeatedly scans a subject with the measurement light, and that causes a detector to detect interference between reflected light of the measurement light and the reference light, and a processor. The processor performs an acquisition process of are temporally sequentially acquiring tomographic images at the same transverse position in the subject based on a signal output from the detector. The processor performs a video image generation process of generating a synthetic image on a real time basis by synthesizing a new tomographic image frequently and one or more past images, and causing a monitor to display a real time video image formed from the synthetic image.

Abstract: An optical tomographic image photographing apparatus for acquiring information on a tissue inside a specimen, the apparatus includes: a synthesis unit configured to generate a interference beam by synthesizing a measuring beam reflected from the tissue and a reference beam; and a detector configured to detect the generated first interference beam as a first interference signal, the first interference beam being detected for each scanning position of the measuring beam. The optical tomographic image photographing apparatus acquires tomographic information for each scanning position of the specimen by using the detected first interference signal and acquiring tomographic image data of the specimen expressed by polar coordinates by using the tomographic information; and converts the tomographic image data of the specimen expressed by the acquired polar coordinates into image data expressed by rectangular coordinates.
