摘要： A light sensing module includes a substrate, a light sensing unit, a first light-transmissive component, and a light shielding layer. The light sensing unit is disposed on the substrate to sense an intensity of a working light beam, and has an upper light receiving surface and a lateral surface perpendicular to the upper light receiving surface. The first light-transmissive component covers the light sensing unit, and has a first refractive index between a refractive index of the light sensing unit and a refractive index of air. The light shielding layer surrounds the lateral surface and is covered by the first light-transmissive component.

摘要： A device includes a scattering structure and a collection structure. The scattering structure is arranged to concurrently scatter incident electromagnetic radiation along a first scattering axis and along a second scattering axis. The first scattering axis and the second scattering axis are non-orthogonal. The collection structure includes a first input port aligned with the first scattering axis and a second input port aligned with the second scattering axis. A method includes scattering electromagnetic radiation along a first scattering axis to create first scattered electromagnetic radiation and along a second scattering axis to create second scattered electromagnetic radiation. The first scattering axis and the second scattering axis are non-orthogonal. The first scattered electromagnetic radiation is detected to yield first detected radiation and the second scattered electromagnetic radiation is detected to yield second detected radiation. The first detected radiation is phase aligned with the second detected radiation.

摘要： The present disclosure relates to limitation of noise on light detectors using an aperture. One example embodiment includes a system. The system includes a lens disposed relative to a scene and configured to focus light from the scene onto a focal plane. The system also includes an aperture defined within an opaque material disposed at the focal plane of the lens. The aperture has a cross-sectional area. In addition, the system includes an array of light detectors disposed on a side of the focal plane opposite the lens and configured to intercept and detect diverging light focused by the lens and transmitted through the aperture. A cross-sectional area of the array of light detectors that intercepts the diverging light is greater than the cross-sectional area of the aperture.

摘要： An apparatus for measuring characteristics of an electronic display panel includes an array of optical elements. Each optical element has a first surface and a second surface. The first surface faces the electronic display panel and receives light from pixels of the electronic display panel. The second surface faces away from the electronic display panel and has an area smaller than the area of the first surface. The second surface emits a combined version of the light received by the first surface. The apparatus further includes a light sensor facing the second surface to measure one or more parameters of the emitted light.
