  • Patent number: 11815665
    Abstract: The disclosure discloses a large-aperture infrared metalens camera, which belongs to the technical field of infrared imaging and micro-nano photonics, including a large-aperture metalens, an infrared focal plane array detector, a metalens mechanical assembly and a housing. The large-aperture metalens has an aperture greater than 50 mm and a thickness less than 2 mm, and the distance between the large-aperture metalens and the infrared focal plane array detector is greater than 30 mm. The disclosure adopts strict electromagnetic field values, diffraction design algorithm and large-area semiconductor process manufacturing method to increase the aperture of metalens to 50 mm or more, and considerably improves the focal length and magnification of the camera while ensuring that the F-number of the metalens meets the requirements of signal-to-noise ratio of image. The problems of short focal length, small magnification, and insufficient imaging range of conventional metalens cameras are overcome.

The large-aperture metalens has an aperture greater than 50 mm and a thickness less than 2 mm, and the distance between the large-aperture metalens and the infrared focal plane array detector is greater than 30 mm. The metalens mechanical assembly uses a buffer structure to fix, adjust and protect the metalens from shocks. The housing is sealed through a thermal insulation coating, thus providing heat insulation and waterproof protection for the lens.

  • Patent number: 8848532
    Abstract: A data processing method and system and relevant devices are provided to improve the processing efficiency of cores. The method includes: storing received packets in a same stream sequentially; receiving a Get_packet command sent by each core; selecting, according to a preset scheduling rule, packets for being processed by each core among the stored packets; receiving a tag switching command sent by each core, where the tag switching command indicates that the core has finished a current processing stage; and performing tag switching for the packets in First In First Out (FIFO) order, and allocating the packets to a subsequent core according to the Get_packet command sent by the subsequent core after completion of the tag switching, so that the packet processing continues until all processing stages are finished. A data processing system and relevant devices are provided. With the present invention, the processing efficiency of cores may be improved.
