摘要： A diffractive waveguide element for a personal display device includes a display waveguide extending in a waveguide plane, an in-coupling diffractive optical element arranged onto or into the display waveguide for diffractively coupling light rays into the display waveguide, and an out-coupling diffractive optical element arranged onto or into the display waveguide for coupling the diffractively coupled light rays out of the display waveguide. In addition, there is provided a ray multiplier element optically upstream of the out-coupling diffractive optical element, the ray multiplier element being capable of splitting a light ray incoming to the in-coupling grating into a plurality of parallel rays spatially displaced in the waveguide plane before they enter the out-coupling diffractive optical element. A waveguide display device is also provided.

摘要： A method for displaying virtual content to a user, the method includes determining an accommodation of the user's eyes. The method also includes delivering, through a first waveguide of a stack of waveguides, light rays having a first wavefront curvature based at least in part on the determined accommodation, wherein the first wavefront curvature corresponds to a focal distance of the determined accommodation. The method further includes delivering, through a second waveguide of the stack of waveguides, light rays having a second wavefront curvature, the second wavefront curvature associated with a predetermined margin of the focal distance of the determined accommodation.

摘要： An optically variable security element has a multicolored, reflective areal region including a first relief structure disposed at a higher level than a second relief structure. The first relief structure has a first ink coating and the second relief structure has a second, different ink coating. The two relief structures overlap in an overlap region. The first ink coating of the first relief structure is disposed at a higher level in the overlap region and has at least one recess the dimension of which is more than 140 μm. The first ink coating comprises an edge region adjoining the recess, and as a bicolor register feature the first relief structure lets the edge region of the first ink coating appear with a first color impression and the second relief structure through the recess lets the second ink coating appear with a second, different color impression in mutual register.

摘要： An optical processor is presented for applying optical processing to a light field passing through a predetermined imaging lens unit. The optical processor comprises a pattern in the form of spaced apart regions of different optical properties. The pattern is configured to define a phase coder, and a dispersion profile coder. The phase coder affects profiles of Through Focus Modulation Transfer Function (TFMTF) for different wavelength components of the light field in accordance with a predetermined profile of an extended depth of focusing to be obtained by the imaging lens unit. The dispersion profile coder is configured in accordance with the imaging lens unit and the predetermined profile of the extended depth of focusing to provide a predetermined overlapping between said TFMTF profiles within said predetermined profile of the extended depth of focusing.

摘要： A system may comprise a selectively transparent projection device for projecting an image toward an eye of a viewer from a projection device position in space relative to the eye of the viewer, the projection device being capable of assuming a substantially transparent state when no image is projected; an occlusion mask device coupled to the projection device and configured to selectively block light traveling toward the eye from one or more positions opposite of the projection device from the eye of the viewer in an occluding pattern correlated with the image projected by the projection device; and a zone plate diffraction patterning device interposed between the eye of the viewer and the projection device and configured to cause light from the projection device to pass through a diffraction pattern having a selectable geometry as it travels to the eye.

摘要： Provided is a Fourier transform-type spectroscopic device capable of improving an acquisition speed of a molecular vibration spectrum. The Fourier transform-type spectroscopic device (1) of the present invention rotates a scanning mirror (26b) by rotation of a rotating shaft (26a) to change a light path length of scanning light and delay or advance the scanning light with respect to reference light in accordance with a rotation angle of the scanning mirror (26b) from an initial position, and is thus capable of moving the scanning mirror (26b) at a high speed as compared with a case where a movable mirror is mechanically moved as in a conventional Fourier transform-type spectroscopic device, thereby improving an acquisition speed of a molecular vibration spectrum.

摘要： A structured illumination microscope device includes acquisition unit that repeats a series of processing steps including controlling a combination of a wave vector and phase of fringes and acquiring N images; and computing unit in which processing for demodulating the image of the sample using a required M types of images from an image set of consecutive P images. The M types of images include: Q types (where Q≥3) of modulated images; and one type of modulated image having the wave vector in common with and the phase differing from at least one among the Q types of modulated images, or one unmodulated image.An arrangement of the N images satisfies the uniformity condition, meaning “intensity distribution of the fringes is spatially uniform when accumulated between the N images” and the refresh condition, meaning “the M types of images are always included in the image set”.

摘要： It is described a method for the production of a fully or partially reflective stretchable and deformable optical element, comprising the implantation in at least one surface of an elastomeric support, by a technique of “Cluster Beam Implantation”, of neutral nanoclusters of a material selected among one or more metals, their alloys, their oxides or mixtures thereof, thus obtaining in said support a nanocomposite layer, possibly emerging at the surface of said element, and said implantation taking place by: uniformly implanting said nanoclusters in a surface of said elastomeric support, wherein said surface has a molded profile essentially corresponding to the profile of the optical element to be produced; or selectively implanting said nanoclusters in a flat surface of said elastomeric support; or uniformly implanting a first layer of said nanoclusters in a surface of said elastomeric support, and then selectively implanting a second layer of said nanoclusters onto the first nanoclusters layer thus obtained.
