  • Patent number: 12140699
    Abstract: A method of manufacturing an optical sensor arrangement including the steps of providing a substrate having a surface and providing an integrated circuit comprising an optical detector arranged for detecting light of a desired wavelength range. The integrated circuit and a light emitter are mounted onto the surface, wherein the light emitter is arranged for emitting light in the desired wavelength range. The integrated circuit and the light emitter are electrically connected to each other and to the substrate. A light barrier is formed between the optical detector and the light emitter by dispensing a first optically opaque material along a profile of the integrated circuit. A mold layer is formed by at least partly encapsulating the substrate, the integrated circuit and the light emitter with an optically transparent material. A casing, made from a second optically opaque material, is mounted on the light barrier and thereby encloses a hollow space between the casing and the mold layer.

  • Publication number: 20240337774
    Abstract: An apparatus includes, in some implementations, at least one image sensor, a plurality of metalenses, and readout and processing circuitry. The at least one image sensor includes pixel arrays, each of which is associated, respectively, with a different one of multiple optical channels configured for detection of incoming light rays of a respective color. The color for each optical channel differs from that of at least one of the other optical channels. Each of the metalenses is disposed, respectively, in a different one of the optical channels and is configured, respectively, to focus incoming light rays onto a different one of the pixel arrays. The readout and processing circuitry is operable to read out signals from the pixel arrays and to generate a respective lower-resolution image for each of the optical channels, and to process the lower-resolution images to obtain a higher-resolution multi-color image. Methods of operation are described as well.
