Abstract: Provided is an ophthalmic apparatus including: an optical head portion including an optical system arranged to measure an eye to be inspected; a movable portion arranged to move the optical head portion in a horizontal direction relative to a base portion; an operation stick, which includes an urging portion arranged to apply an urging force between the base portion and the movable portion, and is provided on the movable portion so as to be tiltable; and an urging force reduction mechanism arranged to reduce the urging force when the operation stick is tilted by a predetermined angle or larger.

Abstract: An ophthalmologic imaging apparatus includes a housing configured to include an optical system that irradiates a subject's eye with measurement light and receives returning light returned from the subject's eye irradiated with the measurement light, a rotation unit configured to rotate the housing by making a predetermined position on an optical axis of the optical system as a rotation center, a position changing unit configured to change a position of the rotation center on the optical axis of the optical system, and a holding unit configured to hold a positional relationship between the housing and the subject's eye when the position of the rotation center on the optical axis of the optical system is changed.

Abstract: Provided is an imaging apparatus, including: a light source which irradiates light that is frequency swept; an interference unit which diverges the irradiation light into irradiation light, which is to be irradiated on an object to be inspected, and reference light, to generate coherent light from reflected light of the irradiation light from the object to be inspected and the reference light; at least two conversion units which subject at least two analog signals, which are obtained by diverging an analog signal of the coherent light, to analog-to-digital conversion; an association unit which associates indices of at least two data arrays obtained by the analog-to-digital conversion; an integration unit which integrates the at least two data arrays based on the associated indices; and an image generating unit which generates an image of the object to be inspected based on a data array obtained by the integration.

Abstract: An ophthalmic imaging apparatus performs imaging to produce a tomographic image of a fundus of an examined eye based on interference light obtained by combining measurement light and reference light, determines whether aliasing has occurred in the tomographic image, when it is determined that the aliasing has occurred, moves a position in which an optical path length of the measurement light and an optical path length of the reference light match from a retina side to a choroid side of the examined eye, and generates a fundus image based on the tomographic image that has been produced through imaging in a state where the position has been moved to the choroid side.
