Japanese Patent JP6628589
Kind Code:
B2
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 member 28 having a transmission pattern where the high transmission parts P1 and the low transmission parts P2 are alternately arranged is placed on a side opposite to the spheroid Sp (imaging object) across the objective lens 27. The transmission pattern is rotationally symmetric with respect to an optical axis AX of the objective lens 27 and 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.
