Abstract:
1. An optical tomographic imaging apparatus for obtaining at least a tomographic image of an object based on a plurality of interference lights obtained by interfering (a) a plurality of return lights from the object irradiated with a plurality of measurement lights and (b) a plurality of reference lights corresponding to the plurality of measurement lights, the apparatus comprising: an irradiation unit for irradiating the object with the plurality of measurement lights; and an optical property adjusting unit for adjusting an optical property of at least one of (a) the plurality of measurement lights, (b) the plurality of reference lights, and (c) the plurality of interference lights, wherein the plurality of measurement lights are divided into a plurality of groups, each group including measurement lights having substantially the same distance between an optical axis of the irradiation unit and that of each measurement light, and wherein the optical property adjusting unit applies the same adjusting method for at least one of (a) the measurement lights, (b) reference lights corresponding to the measurement lights, and (c) interference lights obtained by interfering (i) return lights from the object irradiated with the measurement lights and (ii) the reference lights, in a group of the plurality of groups, and applies a different adjusting method for a different group of the plurality of groups.
