    摘要: The invention provides an apparatus for fabricating a periodic micro-pattern by laser beams. The apparatus includes an ultrafast laser light source configured to generate an output laser beam. A diffraction optical element is configured to divide the output laser beam into a plurality of diffractive laser beams. A confocal system is configured to focus the plurality of diffractive laser beams on a focal point, so that the plurality of diffractive laser beams produces an interference light beam with interference phenomena. The interference light beam ablates a surface of an element to fabricate a periodic micro-pattern on the surface of the element. The confocal system includes a first lens, a second lens and a light shielding mask. The plurality of diffractive laser beams passes through the first lens, the light shielding mask and the second lens in sequence.

    摘要: Multibeam diffraction grating-based color backlighting includes a plate light guide, a multibeam diffraction grating at a surface of the plate light guide, and light sources laterally displaced from one another in a direction corresponding to a propagation axis of the plate light guide. The light sources produce light of different colors. The plate light guide is to guide light from the light sources. The multibeam diffraction grating is to couple out a portion of the guided light using diffractive coupling as a plurality of light beams of different colors in a plurality of different principal angular directions.

    摘要: An optical module includes a transparent substrate and a refractive optical element mounted on the substrate. A conductive heating trace is deposited on the substrate around the refractive optical element. A temperature sensor senses a temperature of the substrate. Control circuitry is coupled to the temperature sensor so as to measure a difference between the temperature of the substrate and a target operating temperature of the module, and to drive a current through the conductive heating trace, responsively to the difference, so as to heat the substrate to the target operating temperature.

    摘要: A projector includes a light source device, a diffraction element that converts light from the light source device into 0-th order light and diffracted light, a light modulation device that modulates the diffracted light so as to form image light, and a projection optical system that emits projected light having a chief ray which is tilted with respect to an optical axis of the image light incident from the light modulation device. Defining a reference plane as a plane which is perpendicular to a plane including the optical axis and a chief ray of the projected light and includes the optical axis, a plane including an optical axis of the 0-th order light and a chief ray of the diffracted light intersects the reference plane.
