Title:
OPHTHALMOLOGICAL IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/073413
Kind Code:
A1
Abstract:
An ophthalmological imaging device according to an embodiment of the present invention includes an objective lens, an interference optical system, an image formation unit, an optical member, and an analysis unit. The interference optical system divides light from a light source into measurement light and reference light, uses the objective lens to cause the measurement light to become incident on an eye under examination, and detects interference light between the reference light and return light of the measurement light that has exited from the eye under examination and passed through the objective lens. The image formation unit forms an image of the eye under examination on the basis of detection results related to the interference light which are acquired by the interference optical system. The optical member is capable of being disposed in the optical path of the measurement light, and absorbs the measurement light. The analysis unit analyses first detection results related to the interference light which are acquired by the interference optical system while the optical member is in a state of being disposed in the optical path, and second detection results related to the interference light which are acquired by the interference optical system while the optical member is in a state of having been removed from the optical path, to eliminate noise in the second detection results or in an image based on the second detection results.
