Abstract

An OCT imaging technique capable of suppressing image noise due to reflection on a wall surface of a carrier for carrying an imaging object by a simple configuration is provided. A light regulating memberhaving a transmission pattern where the high transmission parts Pand the low transmission parts Pare alternately arranged is placed on a side opposite to the spheroid Sp (imaging object) across the objective lens. The transmission pattern is rotationally symmetric with respect to an optical axis AX of the objective lensand a point located at a position point-symmetric with an arbitrary point in the high transmission part with respect to a point where the optical axis of the objective lens intersects with the light regulating surface is included in the low transmission part.
