摘要： A light-trapping image sensor includes a pixel array and a lens array. The pixel array is formed in and on a semiconductor substrate and including photosensitive pixels each including a reflective material forming a cavity around a portion of semiconductor material to at least partly trap light that has entered the cavity. The cavity has a ceiling at a light-receiving surface of the semiconductor substrate, and the ceiling forms an aperture for receiving the light into the cavity. The lens array is disposed on the pixel array. Each lens of the lens array is aligned to the aperture of a respective cavity to focus the light into the cavity through the aperture.

摘要： A method of producing a mold for a microlens array with a cutting tool rotating around a rotation axis, microlenses having the substantially same shapes. A z-axis of an (x, y, z) coordinate system is in the direction of the central axis of a surface of the mold. The method includes the steps of cutting a surface of the mold while each of angle θ between the rotation axis of the cutting tool and a straight line passing through a point on the rotation axis and parallel to the z-axis and angle φ of a plane containing the rotation axis and the straight line around the straight line is kept constant; and cutting the plural surfaces while the values of angle θ and angle φ are determined such that a variance of the values of at least one of angle θ and angle φ is greater than a predetermined value.

摘要： A light field near-eye display device and a light field near-eye display method are provided. The light field near-eye display device includes a processor, a display panel, and a lens module. The processor calculates new ray tracing data based on a current eye relief, preset eye relief data, and preset ray tracing data, and adjusts preset image data according to the new ray tracing data to generate adjusted image data. The display panel is coupled to the processor and emits an image beam according to the adjusted image data. The lens module includes a microlens array and is disposed between the display panel and a pupil. The image beam is incident to the pupil through the lens module and displays a light field image.

摘要： The present invention relates to dust concentration measurement and to dust composition and particle size determination. Multimodal dust sensor is able to simultaneously determine the concentration, size and origin of dust particles in real time. Method of operation of a single measurement channel of the multimodal dust sensor comprises: collimating laser radiation; splitting the laser radiation into two beams: a first beam and a second beam; and focusing the first beam to form a probe volume, wherein a dust particle entering the probe volume: a) scatters the first beam, thereby providing a homodyne mode of operation, in which the second beam and the scattered first beam are combined; the combined radiation falls on the photodetector that registers the Doppler effect; and/or b) fluoresces, thereby providing a fluorescent mode of operation, in which the fluorescent light falls on the photodetector that registers the fluorescent light.

摘要： An optical device comprises a waveguide core layer that includes a planar lens structure having a first end and a second end, with the planar lens structure including a plurality of lens tapers extending from at least one of the first or seconds ends in a convex-shaped array. The waveguide core layer also includes a waveguide slab that adjoins with the planar lens structure, such that the waveguide slab is in optical communication with the plurality of lens tapers. The plurality of lens tapers are configured to adiabatically transition an index of refraction from a first index value, external to the planar lens structure, to a second index value, internal to the planar lens structure.
