Abstract: A computer-implemented method for modeling fabrication constraints of a fabrication process is described. The method includes receiving training data including pre-fabrication structures and post-fabrication, training a fabrication constraint model by optimizing parameters of the fabrication constraint model based on the training data to model the fabrication constraints of the fabrication process, receiving an input design corresponding to a physical device, and generating a fabricability metric of the input design via the fabrication constraint model. The fabricability metric is related to a probabilistic certainty that the input design is fabricable by the fabrication process determined by the fabrication constraint model.

Abstract: The present invention provides a method for performing optical image detection using a camera module comprising a Digital MicroMirror Device, a first point Photo Detector, a second point Photo Detector, a first lens and a second lens. The method comprises: mapping incident light onto an image plane of the DMD to form a light irradiance map; selecting N pixels on the DMD for time frequency coding; associating each selected pixel with a unique Walsh code time sequence; time frequency coding by the DMD the optical irradiance values of each selected pixel using a plurality of selected bits of its associated Walsh code time sequence; detecting the time frequency coded optical irradiance values of the selected pixels simultaneously at the first point Photo Detector and at the second point Photo Detector; and performing simultaneous signal processing on the time frequency coded optical irradiance values detected by the first point Photo Detector and by the second point Photo Detector to determine the light intensity of each of the selected pixels and produce an image of the incident light.

Abstract: A passive speckle-suppressing diffuser includes a microlens array for diffusing a light field originating from one or more coherent light beams, and a diffractive optical element mounted in series with the microlens array and having a pixelated thickness distribution, characterized by a spatial variation across the diffractive optical element, to impose a spatially varying phase shift on the light field. The pixelated thickness distribution may be configured such that the spatially varying phase shift suppresses speckle of the light field while minimizing introduction of distinct diffraction structure. A method for passive speckle-suppressing diffusion a light field originating from one or more coherent light beams may include refracting the light field, through a microlens array, to diffuse the light field, and imposing a spatially varying phase shift on the light field to decohere the light field without introducing any first-order diffraction components deflected beyond angle spread introduced by the microlens array.

Abstract: A display may include an optical emitter that emits infrared light, a first coupler that couples the infrared light into a waveguide, and a second optical coupler that couples the infrared light out of the waveguide and towards the eye box. The infrared light may reflect off an eye as reflected light. The second optical coupler may couple the reflected light into the waveguide and the first optical coupler may couple the reflected light out of the waveguide and towards a camera for performing gaze tracking operations based on the sensor data. The display may sequentially illuminate different regions of the eye with the infrared light at different times using a scanning mirror, an array of light sources, or a wavelength-adjustable light source and gratings. This may minimize infrared light scattering, which minimizes background generation and maximizes signal-to-noise ratio for gaze tracking operations.

Abstract: A light transmissive structure includes a light transmissive substrate having first and second opposing faces, and an array of microprism elements on the first face. Each microprism element includes a first inclined surface disposed at a first inclined angle relative to the second face, and a second inclined surface disposed at a second inclined angle relative to the second face. The first inclined angle is less than the second inclined angle, and a peak angle between the first inclined surface and second inclined surface is in the range of about 70 degrees to about 100 degrees. The second inclined surface has a convex curvature when viewed from angles perpendicular thereto. The light transmissive structure is configured to receive light from a light source facing the first face in a first direction and redistribute light emerging from the second face in a second direction different from the first direction.

Abstract: A ceiling grid lighting assembly for use in suspended ceiling systems is provided with multiple linear lighting modules in parallel arrangement. End plates are used to connect, support, and enclose longitudinal ends of the elongate body of each linear lighting modules while simultaneously functioning as reflective faces for optical cavities. A configured gap spacing between individual linear lighting modules can be used to house and support components such as additional light sources, acoustic or decorative panels, HVAC components, or power systems, controls or sensors. The end plate can also be configured to allow a T-bar to be placed in the configured gap spacing thereby enabling the mounting of the assembly in-line upon the longitudinal axis of a ceiling grid T-bar. Embodiments of linear lighting modules are presented comprising LED light sources, light guides and diffusers housed within the elongate body. The light guides may be edgelit from one or two sides and aligned horizontally or tilted relative to the ceiling grid plane.

Abstract: An anti-glare film is attached on a surface of a display, and includes an anti-glare layer. The anti-glare layer is set to have a sparkle value falling within a range from 6 to 10, which is defined based on a value of a standard deviation of luminance distribution of the display under a state in which the anti-glare film is attached on the surface of the display, a value of specular gloss of 30% or less, which is measured with 60-degree specular gloss, a value of transmission image clarity of 60% or less, which has an optical comb of 0.5 mm, and a haze value of 50% or less. Consequently, satisfactory anti-glare property can be provided while appropriately suppressing sparkle on the display.
