Title:
眼科装置、及びその制御方法
Document Type and Number:
Japanese Patent JP7134014
Kind Code:
B2
Abstract:
An ophthalmologic apparatus includes a refractometry optical system, an OCT optical system, a fixation projection system, and a controller. The refractometry optical system is configured to project light onto a subject's eye and to detect returning light from the subject's eye. The OCT optical system is configured to split light from an OCT light source into measurement light and reference light, to project the measurement light onto the subject's eye, and to detect interference light between returning light of the measurement light from the subject's eye and the reference light. The fixation projection system is configured to simultaneously project a first fixation target and a second fixation target onto the subject's eye, a visual angle of the second fixation target being narrower than a visual angle of the first fixation target. The controller is configured to control the refractometry optical system and the OCT optical system to simultaneously perform a refractometry and an OCT measurement.
