    摘要: The present invention relates to an autostereoscopic display device, comprising an imaging layer (9) and a lens layer (10). The lens layer (10) serves to project different content from the imaging layer (9) to the left and right eyes, respectively, of a user. The lens layer (10) comprises lens cells (12), enclosing two fluids (13, 14) with different refractive indices. The shape of the interface between the fluids may be changed using electrowetting, by means of two individually controllable electrodes (21, 22) at the sides of each lens cell (12). The display device further comprises a user head tracking device and means for controlling the lens cell electrodes depending on a detected user head position. This allows the display device to display a correct 3D-image, even if the user moves his head.

    摘要: An acoustic probe (100, 300) includes an acoustic transducer (15, 444), and a plurality of variably-refracting acoustic lens elements (10, 210a, 210b, 442) coupled to the acoustic transducer. Each variably-refracting acoustic lens element has at least a pair of electrodes (150, 160) adapted to adjust at least one characteristic of the variably-refracting acoustic lens element in response to a selected voltage applied across the electrodes. In one embodiment, each variably-refracting acoustic lens element includes a cavity, first and second fluid media (141, 142) disposed within the cavity, and the pair of electrodes. The speed of sound of an acoustic wave in the first fluid medium is different than the speed of sound of the acoustic wave in the second fluid medium. The first and second fluid media are immiscible with respect to each other, and the first fluid medium has a substantially different electrical conductivity than the second fluid medium.

    摘要: The disclosure is directed to a system for variably refracting, and is transparent for, ultrasound as well as for light. By choosing liquids with the right optical and acoustical properties, it is possible to variably refract (including focusing and deflecting or steering) ultrasound while not affecting the refraction of light, or vice versa. Two lenses in series, or preferably one lens, allow for variably refracting ultrasound and light.

    摘要: An imaging system with two modalities has a catheter with an optical lens system situated at an end of the catheter and optically connected to optical guide. The lens system has a numerical aperture which is changeable between a first aperture and a second larger numerical aperture. The imaging system also has an imaging unit for optical imaging with the catheter. First and second imaging modalities are optically connectable with the optical lens system of the catheter. The imaging system can change between imaging in two modes: (1) the first numerical aperture of the optical lens system and the first imaging modality of the imaging unit, and (2) the second numerical aperture of the optical lens system and the second imaging modality of the imaging unit.

    摘要: An objective lens system for an optical biopsy device has a lens that comprises a first part configured for viewing at a first magnification, and a second part configured for viewing at a second magnification. The second magnification is substantially different from the first magnification. The first magnification enables viewing a larger area of a target and the second magnification enables viewing the target at a cellular level with high sensitivity and specificity. Combining viewing at two different magnifications in a single objective lens results in a compact optical biopsy device.
