  • Publication number: 20230325993
    Abstract: An X-ray imaging device includes an X-ray irradiation module, an X-ray detection module and an image processor. The image processor is configured to perform: acquiring a high-energy image and a low-energy image respectively obtained by X-ray of relatively high-energy and X-ray of relatively low-energy; generating high-energy frequency component images for each of a plurality of frequency bands by decomposing the high-energy image; generating low-energy frequency component images for each of a plurality of frequency bands by decomposing the low-energy image; generating merged frequency component images by merging at least a portion of the high-energy frequency component images for each of the plurality of frequency bands and at least a portion of the low-energy frequency component images for each of the plurality of frequency bands; and generating a standard image using the merged frequency component images.

  • Patent number: 10353268
    Abstract: Provided are an acousto-optic element, an acousto-optic element array, and a display apparatus including the acousto-optic element array. The acousto-optic element includes: an acousto-optic modulator which includes an acousto-optic layer formed of an acousto-optic material; a light supplier which supplies light to the acousto-optic modulator in a first direction; a first sound-wave modulator which applies first elastic waves to the acousto-optic modulator in a second direction; and a second sound-wave modulator which applies second elastic waves to the acousto-optic modulator in a third direction. The light supplied from the light supplier to the acousto-optic modulator is deflected by diffraction caused by the first elastic waves applied from the first sound-wave modulator and diffraction caused by the second elastic waves applied from the second sound-wave modulator, and is output from the acousto-optic modulator through a front side of the acousto-optic modulator.
