    摘要： An optical diffraction element (1) comprises a diffraction layer (4) which is divided into diffraction strips (6) alternating with intermediate strips (8). The diffraction strips comprise nano-elements (10) which are aligned in one direction and absorb radiation (b) which is linearly polarized in this direction. The diffraction element may be a linear or two-dimensional grating (1) or a Fresnel lens (160). The polarization-sensitive grating can be used in optical systems in which only radiation with a specific polarization direction should be diffracted, or in an optical record carrier to allow reading of an information structure with high spatial frequencies.

    摘要： A display device is provided in which the electro-optical effect is created through bending of bendable elements, particularly nanowires or nanotubes. Arrays of bendable elements are provided in areas of the display with the light path. This is possible in that the bendable elements are transparent in the case where they are oriented substantially perpendicular to the substrate, but will absorb light if bent at an angle. Hereto, it is of importance that polarized light is used. The bendable elements are preferably separated from the electrodes through a layer of dielectric material, and are bent under the influence of an electric or magnetic field.

    摘要： The invention relates to a method and device (1) for imaging an interior of a turbid medium (55). A turbid medium (55) inside a measurement volume (15) is irradiated from a plurality of source positions (25a) with light from a light source (5), and light emanating from the measurement volume (15) is detected from a plurality of detection positions (25b). An image of the interior of the turbid medium (55) is reconstructed from the detected light. In both the method and the device (1), detector signals can be amplified for each source position-detection position pair by a multi-gain amplification unit comprising an amplifier circuit (60). The amplification factor is selected from a number of possible amplification factors based on detected signal strength in the prior art. According to the invention, however, the method and device are adapted such that the amplification factor is selected for at least one source position-detection position pair on the basis of an estimate of expected electrical signal strength.

    摘要： The invention discloses an optical microscopy system (10) for stimulated emission depletion (STED) of an object (O). An optical element (6) is applied for focusing a first excitation (1) and a second depletion (2) beam on the object thereby defining a common optical path (OP) for both the first and the second beam. A phase modifying member (5) is inserted in the common optical path (OP), and the phase modifying member is optically arranged for leaving the wavefront of the first beam substantially unchanged, and for changing the wavefront of the second beam (2′) so as to create an undepleted region of interest (ROI) in the object. The first beam and the second beam have a common optical path because the phase modifying member adapts the wavefront or phase in such a way that it has no effect on the first beam, while on the second beam it gives rise to a wavefront, or phase change, resulting in a depleted region in the object (e.g. to the donut shaped spot) at the focal plane. The invention facilitates smaller and/or improved optical designs for STED microscopy; this is particularly relevant for medical in-vivo imaging, e.g. endoscopes and catheters.

    摘要： An apparatus, system and method determining a position of an instrument (100) are provided. A sheath (104) is configured to fit within an instrument channel of a medical scope. An optical fiber (112) is disposed within the sheath and a plurality of sensors (106) is integrated in optical fiber.
