Examination instrument


Light from an exit pupil of an illumination unit is directed to a beam splitter which directs the light to an objective. The retina is illuminated, if a real image of the exit pupil of the illumination unit and a real image of an entrance pupil of a camera unit are formable in a position ranging from the cornea to the backside of the crystalline lens with the light.

Intraocular expansion and retention devices and methods


An intraocular expansion and retention device (“ierd”) expands the iris, enlarging the pupil during intraocular surgery, and can be removed following the procedure without damaging the eye tissue. The intraocular expansion and retention device includes a number of stepped blades that form pockets to cup the iris margins and expand the pupil allowing increased visualization during intraocular surgery..

Scanning optical microscope


A scanning optical microscope includes a light source, a light converging optical system, a stage, a scanning unit which displaces an illumination light and the stage relatively, a detecting optical system, and a photodetector. A light modulation element and a relay optical system are disposed on the light converging optical system side of the light source, and a modulated signal having only amplitude changed is input to the light modulation element, and the light modulation element is positioned such that the illumination light emerged from the light modulation element with respect to the modulated signal of a predetermined amplitude coincides with an optical axis of the light converging optical system, and a position of a pupil of the light converging optical system and a position of the light modulation element are conjugate through at least the relay optical system..

Electronic ophthalmoscope for selective retinal photodisruption of the photoreceptor mosaic


An electronic slo/oct ophthalmoscope is equipped with a femtosecond (fs) laser for intra- or preretinal therapeutic use in the posterior segment of the eye. In one application the retina photoreceptor mosaic or bruch's membrane is disrupted in such pattern that minimizes loss of visual functioning but reduces metabolic load of the outer retina.

Image generation method, image generation apparatus, program, and storage medium


An image generation method is provided for generating an output image from an input image acquired by an image sensor that has an array of multiple pixels, each of which has arranged therein multiple sub-pixels that each receive a light beam that passes through a different pupil sub-area of an imaging optical system. The method includes a step of generating multiple parallax images that respectively correspond to the different pupil sub-areas; a step of generating multiple pixel shifted images by performing different shifting for each of the parallax images according to a virtual image forming plane of the imaging optical system; and a step of generating an output image that has a higher resolution than the resolution of the parallax images from the pixel shifted images through composition processing..
