  • Patent number: 12025497
    Abstract: A high-resolution spectral image fast acquisition apparatus comprises an illumination source, an objective lens, a beam splitter, a single shot spectral image acquisition assembly and a reference image acquisition assembly, wherein the objective lens is used to align a sample to be measured; the illumination source is used to project an illumination light onto the sample to be measured so that the sample to be measured is amplified by the objective lens; wherein one part of amplified light enters the single shot spectral image acquisition assembly so as to acquire a low-resolution spectral cube of the sample to be measured, and another part of the amplified light enters the reference image acquisition assembly to acquire a high-resolution spectral cube. The apparatus enables rapid access to high-resolution spectral images, thereby speeding up the process of using spectral images for medical diagnosis.

  • Publication number: 20230266584
    Abstract: An encoded illumination real-time focusing scanning imaging device includes an LED array, an object stage, an objective lens, a liquid lens, a lens sleeve, and a camera. The object stage is used for placing a sample, the LED array is used for emitting bright field light or encoded light, and the bright field light or the encoded light respectively penetrates through the sample and then successively passes through the objective lens, the liquid lens, and the lens sleeve to reach the camera to shoot a bright field image or an encoded light illumination image by the camera. The present invention also discloses an encoded illumination real-time focusing scanning imaging method, which is performed by using the above-mentioned device. The present invention enables fast and accurate focusing at a low cost.
