Abstract: The present invention provides a projection display comprising an illumination system comprising at least one laser source unit and configured and operable for producing one or more light beams; a spatial light modulating (SLM) system accommodated at output of the illumination system and comprising one or more SLM units for modulating light incident thereon in accordance with image data; and a light projection optics for imaging modulated light onto a projection surface.

Abstract: A method and apparatus for illuminating the interior of the eye through the sclera without any contact to the eye. The apparatus contains a lamp element and optics that focus the light on the eye sclera. One or more fiber optics bundles may be used to convey the light from the light source close to the illuminated eye, ending with condensing optical elements. Alternatively, light could be conveyed by sharing the optics of an imaging system. It is useful for observing or imaging the interior of the eye, the retina, or the choroid. The observation or the imaging of the interior of the eye, the retina, or the choroid by applying the disclosed illumination method can be done in conjunction with any system that includes optics for that purpose, e.g., fundus cameras and ophthalmoscopes, without using those systems' illumination elements.

Abstract: An optical system for receiving an incoming beam of electromagnetic radiation, for dividing it into a transmitted beam, containing a part of the wavelength band of the incoming beam, and a reflected beam, containing the remainder of the wavelengths in the incoming beam, and for transferring the transmitted beam continuously to a detector. The system is capable of switching the reflected beam between any one of two or more detectors. The system comprises an objective lens, a dichroic beamsplitter cube, a first detector, capable of detecting radiation in a first wavelength band, a second group of two or more detectors, each capable of detecting radiation in a second wavelength band and means of rotating the dichroic beamsplitter cube, so as to switch between the detectors of the second group.
