  • Patent number: 11972596
    Abstract: An intelligent smog-penetrating optical imaging detection device and a method of thereof, and belongs to the technical field of photoelectric imaging. The intensity information, the spectrum information, and the polarization information of light are organically combined, the three functions of intensity imaging, spectrum imaging and polarization imaging can be achieved, traditional imaging detection is beneficially supplemented, smog can be penetrated, the image contrast of imaging is improved, and therefore the working distance is increased. The intensity information reflects the detection distance, the target shape, the target size and the like; the spectrum information reflects material components, surface morphology and the like of a space target; the polarization information reflects the material and roughness of the target and the contrast with the background; and the intensity, spectrum and polarization three-dimensional information is jointly applied, the image contrast can be increased by 2-3 times.

  • Patent number: 11929446
    Abstract: Provided is a preparation method of a detector material. The present disclosure epitaxially grows a buffer layer on a surface of a gallium arsenide substrate, deposits a silicon dioxide layer on the buffer layer, and etches the silicon dioxide layer on the buffer layer according to a strip pattern by photolithography and etching to form strip growth regions with continuous changes in width. Finally, a molecular beam epitaxy (MBE) technology is used to epitaxially grow the detector material in the strip growth regions under set epitaxy growth conditions. Because of the same mobility of atoms arriving at the surface of the substrate, numbers of atoms migrating to the strip growth regions are different due to different widths of the strip growth regions, such that compositions of the material change with the widths of the strip growth regions or a layer thickness changes with the widths of the strip growth regions.
