    Abstract: A novel surgical lens system including a lens and a reflective element. The lens is placed on, or above, a cornea of an eye of a subject for enabling inspection of the eye. The reflective element is incorporated into the lens. The reflective element reflects a light beam toward the eye of the subject. The reflective element increases the divergence of the light beam, such that the divergence of the reflected light beam is larger than the divergence of the light beam. The light beam is emitted by a non-invasive light source positioned externally to the eye.

    Abstract: A device for image gating using an array of reflective elements is provided herein. The device includes an array of reflective elements, wherein each one of the reflective elements is movable within a range of a plurality of tilt positions, wherein the array is located at an image plane of the device, wherein the array is perpendicular to an optical axis of the device. The device further includes a control unit configured to control the reflective elements such that in at least some of the tilt positions, the reflective elements reflect the radiant flux at said image plane, to one or more projection planes. A gradual rotation of the reflective elements along the plurality of tilt positions result in a gradual increase or decrease in the intensity of the image reflected from the array of reflective elements while maintaining the image integrity.

    Abstract: Systems and methods are provided for non-invasive detection of blood vessels. The systems and methods cool uniformly a tissue volume below a skin region for a specified cooling period and then image vessel thermal footprints of vessels below the skin as they heat up the skin region. The systems comprise a thermal imaging device configured to image the skin region after the cooling period, an image processor arranged to identify, in images captured by the thermal imaging device, which arise on the skin region after discontinuation of the cooling, and displaying means configured to present the identified vessel thermal footprints. The system and methods may analyze the spatio-temporal patterns of the natural heating of the skin surface to derive data on the location of the vessels under the skin. Three dimensional (3D) imaging optics and techniques may further enhance the vessel imaging.
