Optical tomographic imaging apparatus

摘要

Provided is an optical tomographic imaging apparatus that can suppress variations of resolution, sensitivity, and the like and reduce the number of components for equalizing optical properties so that cost can be reduced, in a case of an OCT apparatus using a plurality of lights. The optical tomographic imaging apparatus for obtaining a tomographic image of an object includes an optical property adjusting unit for adjusting an optical property of at least one light of measurement lights, reference lights, and interference lights each comprised of a plurality of lights. The optical property adjusting unit is shared by each group including measurement lights having substantially the same distance from an optical axis of an irradiation optical system among the measurement lights comprised of a plurality of lights.

主权项

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.
