Abstract: The beam shaper (25A) includes a mode conversion device (27), a collimating lens (28), and a focusing lens (30). The mode conversion device (27) refracts, among laser beams (LB) of incident divergent light, laser beams incident on an outer peripheral side of a central portion (31c) about an optical axis towards the optical axis (Ax) to emit as outer peripheral side beams (NDB1), and emits the laser beams incident on the central portion (31c) as central beams (NDB2) having an angle of emergence equal to an angle of incidence. A collimating lens (28) converts the outer peripheral side beams (NDB1) and the central beams (NDB2) emitted from the mode conversion device (27) into collimated light. A focusing lens (30) focuses the outer peripheral side beams (NDB1) and the central beams (NDB2) emitted from the collimating lens (28) .

Abstract: A lens includes an optically transparent substrate having a first lens surface and a second lens surface opposite to the first lens surface. The first lens surface includes a plurality of Fresnel structures. A respective Fresnel structure of the plurality of Fresnel structures includes a slope facet and a draft facet. The respective Fresnel structure of the plurality of Fresnel structures is characterized by a representative pitch. The representative pitch of the respective Fresnel structure is based on a distance of the respective Fresnel structure from a reference axis of the lens. A display device that includes the lens and an electronic display coupled with the lens for outputting light through the lens and a method for transmitting light from an electronic display toward the lens are also described.

Abstract: A single layer image projection system that Is made up of an arrangement of optionally reflective arcuate elements having an upper arcuate surface, a lower surface, and an arcuate area bounded by the upper arcuate and lower surfaces, and an optionally reflective pattern of image relief microstructures disposed on or within at least some of the upper arcuate surfaces of the arcuate elements, is provided. The arrangement of optionally reflective arcuate elements and the optionally reflective pattern of image relief microstructures are in a single layer and interact to project one or more images. For an upper arcuate surface with convex surface curvature, the image relief microstructures extend downwardly from this surface terminating within the arcuate area, and for an upper arcuate surface with concave surface curvature, the image relief microstructures extend upwardly from this surface terminating within an area defined by the curvature of the upper arcuate surface. Transmission of light through the system, reflection of light from the system, or a combination thereof forms one or more images.

Abstract: A system and method are described for performing tear film structure measurement. A broadband light source illuminates the tear film. A spectrometer measures respective spectra of reflected light from at least one point of the tear film. A color camera performs large field of view imaging of the tear film, so as to obtain color information for all points of the tear film imaged by the color camera. A processing unit calibrates the camera at the point measured by the spectrometer so that the color obtained by the camera at the point matches the color of the spectrometer at the same point. The processing unit determines, from the color of respective points of the calibrated camera, thicknesses of one or more layers of the tear film at the respective points. Other applications are also described.
