Abstract: A multi-focal light-sheet structured illumination system that can be implemented as a part of a commercial fluorescence microscope or a module that is adaptable to fit a number of commercially available microscopes. The system provides simultaneous capture of 2D images from multiple planes within a 3D volume, which are resolved laterally and axially to provide improved resolution along the three dimensions (x,y,z). A Wollaston prism allows several axially-localized high-contrast structured illumination patterns to be generated.

Abstract: A depth detection device includes a stereo image recording device, a scaler and a depth determiner is provided. The stereo image recording device is configured to record a stereo image of a scene, and includes a first optical path for recording a first image of the stereo image, and a second optical path for recording a second image of the stereo image.

The method allows full control over the optical display parameters in Integral Imaging (InI) monitors. From a given collection of elemental images, a new set of synthetic elemental images (SEIs) ready to be displayed in an InI monitor can be calculated, in which the pitch, microlenses focal length, number of pixels per elemental cell, depth position of the reference plane, and grid geometry of the microlens array (MLA) can be selected to fit the conditions of the display architecture.

Abstract: The invention relates to a fundus camera that incorporates an integral imaging system for capturing an integral photograph of the fundus. This integral photograph enables projecting a three-dimensional image and generating topographical maps of the fundus. The fundus camera can function plenoptically and thus zoom onto a two-dimensional image generated from the integral photograph. The proposed equipment consists of an optical system for illuminating the fundus and an optical system forming the integral image capture system. This capture system includes an ophthalmoscopic lens, a microlens array and a sensor, and it allows recording, in a single shot, multiple views of the fundus. To improve the resolution of the integral photograph, the capture system has a device that allows displacing the microlens array by a few microns.
