Patent number: 12025497Abstract: 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.Type: GrantFiled: May 17, 2022Date of Patent: July 2, 2024Assignee: TSINGHUA SHENZHEN INTERNATIONAL GRADUATE SCHOOLInventors: Yongbing Zhang, Kaifa Xin, Xiangyang Ji, Haoqian Wang
