Chlorophyll fluorescent information is closely related to the vital movement of a plant, so it can be used as a probe of the natural environment so as to quickly and accurately reflect the state of the environment around plants. A studying method of the plant leaves chlorophyll fluorescence image combining with remote sensing technology is presented in this paper. The system is designed and established...
The aim of this study is the optimization of Er3+ doped laser glasses which are used for the realization of high power laser amplifier and fiber laser. The Er3+ doped cadmium silicate glasses were fabricated by the technique of high-temperature melting. The emission intensity of 1534 nm near-infrared light pumped at 488 nm, 532 nm and 800 nm laser were compared. The spectral parameters were determined...
The fluorescent spectrometry used for trace amount of sodium determination with high sensitivity has been discussed in this paper, which was based on complexation of ortho-methoxyl tetraphenylporphyrin (o-OCH3TPP) and sodium ion with the excitation wavelength of 242 nm. With the concentration of sodium ion increased, the fluorescence intensity of the complex increased at the emission wavelength of...
The images, in high-throughput genome sequencing of sequencing by synthesize, consist of A, C, G, T base fluorescence images, and the fluorophore emission spectra partially overlap, which causes cross-talk problem. This paper presents a method of correlation analysis, construct the calibration matrix to eliminate interference of the fluorophore. The experiment result shows the method provided in this...
