Imaging spectrum system is designed independently. Imaging spectrum analysis is more convenient and efficient detection method. It can better control the genuineness and the quality of Coriex Phellodendri chinensis raw material and the tablets in the circulation, the production and the clinical use. Appling imaging spectrum analysis, transmission spectra of Coriex Phellodendri chinensis are measured...
The multispectral fluorescence imaging method was presented to identify the species of the cortex phellodendri chinensis pieces. The species character was obtained by the characteristic spectrum got from the spectral cube, whose images were taken for 5 nm spacing from 480nm to 680nm wavelengths by the liquid crystal spectral imaging instrument. As an experiment, ten samples came from ten different...
The multispectral imaging method is presented to test the relative content of berberine of cortex phellodendri chinensis (CP) in vivo. It is the first time that the method is applied to testing the traditional Chinese medicines. The testing system is the liquid crystal multispectral imaging system designed by ourselves. The samples coming from eight different producing areas are tested. As a comparison,...
In order to identify the elements of traditional Chinese medicines (TCMs), the chemical imaging device is designed in this paper. The liquid crystal tunable filters (LCTFs) are adopted to select the spectrum which is the core hardware of the device. After developing corresponding light source, object lens and CCD camera, the chemical images can be captured. By analyzing the images data, the characteristic...
In order to test the content and distribution of elements, a multispectral imaging system is presented in the paper. The liquid crystal tunable filters (LCTFs) are placed into an ordinary optical imaging system as the spectrum-dividing component. The spectrum resolution of the system is up to 0.5 nm, and the spatial resolution depends on the LCTFs, CCD camera and the lenses. The software was also...
