Title:
OPHTHALMOLOGICAL MICROSCOPE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/002379
Kind Code:
A1
Abstract:
The present invention automatically acquires a focused OCT image while an eye under examination is being observed. The ophthalmological microscope system according to the embodiments includes an illumination system, a pair of light-receiving systems, an interference optical system, a movement mechanism, a control unit, and a data-processing unit. The illumination system emits illumination light at an eye under examination. The pair of light-receiving systems include respective objective lenses and imaging elements, are arranged such that the objective optical axes thereof are not parallel to each other, and, via the respective objective lenses thereof, guide return light that is from illumination light that has been emitted at the eye under examination to the respective imaging elements thereof. The interference optical system includes a focus lens and an OCT objective lens, separates light that is from an OCT light source into measurement light and reference light, and detects, via the focus lens and the OCT objective lens, interference light between the reference light and return light that is from measurement light that has been emitted at the eye under examination from a direction that is different from the objective optical axis. The movement mechanism moves the focus lens. The control unit controls the movement mechanism. The data-processing unit generates analysis results or an image of the eye under examination on the basis of the detection results for the interference light.
