Visible and near-infrared spectral reflectances of surface vegetation are basic data for applications in remote sensing classification, multispectral imaging and color reproduction. Leaves are the objects of this study. Firstly, The 400-700 nm visible light spectral reflectance and 700−1000 nm near infrared spectral reflectance data of 12 kinds of trees such as camphor tree, ginkgo tree and peach tree (etc.) are measured by visible and near-infrared portable hyperspectral cameras. The spectral reflectance data is obtained by denoising the using the Minimum Noise Fraction (MNF). Secondly, the Principal Component Analysis (PCA) is used as a method of processing spectral reflectance in the visible and near infrared bands. At last, the correlation analysis is used for spectral reflectance in the visible and near-infrared bands. The obtained data and results provide a theoretical basis for the subsequent establishment of a spectral reflectance data base of surface vegetation spectroscopy and multispectral imaging.
The interaction between laser and C-SQDB bio-molecule which is related with the fluorescence effect, thermal effects
and eliectrical effect from the coupling structure of quantum dots bonded with bio-molecules and of have been wildly researched for the potential application in life science. .As one of the most problems, the electrical effects are analyzed by employing quantum theory in this paper and The research will be conducive to the practical application of C-S QDBS
in medical science.
The red-shift fluorescent is often observed from the biomolecules covalently coupled with the core/shell quantum dots, while blue shift fluorescent from the electrostatic adsorption coupling structures. These fluorescent effect characteristics are analyzed on the basis of the quantum theory of condensed matter, and are demonstrated to be mainly related with the elementary excitation.
The microscopic mechanism of laser-biomolecule interaction is analyzed by quantum theory, including the interactions
of laser with the chain of the biomolecular in the damping case and undamping case. The results show that the
interaction of laser with DNA may result in the system getting into a chaotic state of biomolecules due to damping effect
and changing the original molecular conformational, which will contribute to the improvement of laser medical.
Recently excellent infrared detectors have been demonstrated using InAs/GaSb superlattice materials sensitive at wavelength from 3um to greater than 32um. Using empirical tight binding method (ETBM), different structures as InAs(xML)/GaSb(8ML), (x=2, 4, 6, 8) and InAs(14ML)/GaSb(7ML) were designed for various cut-off wavelengths from short to long IR wavelength. These materials were grown by MBE with valved cracker cells for arsenic and antimony on p-type GaSb(001) substrates. The microstructure and the bandgap Eg were verified by high resolution X-ray diffraction and photoresponse spectra. The temperature dependence of Eg and photoresponse responsivity Rv were studied. The differential resistance under zero bias R0 in MWIR photodiode was measured up to 106 ohms. The ideality factor in the range of 1.5 to 2.1 indicates the generation-recombination current and surface leakage current are the dominant leakage in the depletion region. These results will promote InAs/GaSb superlattices infrared detectors research in multi-color from short to long wave IR application.
Some cases with cerebral infarction were treated by He-Ne laser irradiation on blood.
In the treatment before and after, membrane-cholesterol(C)/membrane-phosphatide(P),
membrane fluidity(F) and deformability of erythrocyte were determined. The results
showed that low level laser irradiation on blood (LLLIB) can sure reduce the ratio of
(C)/(P), can heighten fluidity and improve deformability of erythrocyte .Thus the
metabolism ability of erythrocyte membrane-lipid ,the blood circulation and the
properties of hemorheology can be improved. In this paper, the microscopic
mechanism of those aforesaid action effects by low level laser irradiation on blood
were analyzed by means of Quantum theory and some corresponding models.
