Abstract: In some embodiments, an interconnect electrical connects a light emitter to wiring on a substrate. The interconnect may be deposited by 3D printing and lays flat on the light emitter and substrate. In some embodiments, the interconnect has a generally rectangular or oval cross-sectional profile and extends above the light emitter to a height of about 50 ?m or less, or about 35 ?m or less. This small height allows close spacing between an overlying optical structure and the light emitter, thereby providing high efficiency in the injection of light from the light emitter into the optical structure, such as a light pipe.

Abstract: The invention relates to a device and a method for examining the retinal vascular endothelial function of the vessels of the retina at the fundus (F) of a patient's eye. Using a fundus camera, the vessels of the retina are stimulated with flicker light during a stimulation phase and sequences of images of areas of the fundus (F) are recorded, from which vascular parameters are derived which describe the retinal vascular endothelial function of the vessels. By imaging a macula stop (MB), which covers the macula, onto the fundus (F), the fundus (F) can be illuminated with a higher light intensity, which improves the stimulation effect and the image quality and/or reduces the strain on the patient.

Abstract: A technique for adjusting the brightness values of images to be displayed on a stereoscopic head mounted display is provided herein. This technique improves the perceived dynamic range of the head mounted display by dynamically adjusting the pixel intensities (also known generally as “exposure”) of the images presented on the head mounted display based on a detected gaze direction. The head mounted display includes an eye tracker that is able to sense the gaze directions of the eyes. The eye tracker, head mounted display, or a processor of a computer system receives this information, determines an intersection point of the eye gaze and a screen within the head mounted display and identifies a gaze area around this intersection point. Using this gaze area, the processing system adjusts the pixel intensities of an image displayed on the screen based on the intensities of the pixels within the gaze area.

Abstract: A method of imaging an interior of an eye includes illuminating the interior of the eye with one or more beams of light from a light source, and said illuminating is configured to trigger a change to a pupil of the eye. An image sensor captures a sequence of images of light reflected by the interior of the eye during an expected timeframe when a width of the pupil is changing in response to said illuminating. A processing apparatus combines images in the sequence of images to form a composite image having a larger depth of field than a depth of field of each of the images in the sequence of images. The depth of field for each of the images corresponds to the width of the pupil when each of the images is captured.
