| 英文摘要 | Integrating molecular imaging technology and hyperspectral technology, a novel molecular hyperspectral imaging (MHSI) system based on AOTF was presented. The system consists of microscope, spectrometer, matrix CCD, image collection card and computer. The system's performance was synthetically evaluated referring every part's performance. The spectral range of the MHSI system is from 550 to 1 000 nm. Two hundred twenty five bands can be continuously captured at a time. The spectral resolution is less than 2 nm. The spatial resolution is about 0.061 5 mu m. CCD acquisition speed achieved 2.612 5 s . B-1 in the integration mode and about 0.11 mu s . B-1 in the non-integration mode. Due to the infection of lamp, a spectral curve extracted directly from the original hyperspectral data can not truly present biochemical character and needs to be corrected. The paper proposes the gray correction coefficient algorithm with spatial dimension and spectral dimension, and gives concrete realization of the algorithm. Taking the sample of leukemia blood, by comparing the single-band images, pseudo-color images and spectra before and after correction, the results indicate the effectiveness of correction algorithm. The corrected data is effective for subsequent analysis. |
