Quantitative imaging of KOH vapor in combustion environments using 266 nm laser-induced photofragmentation fluorescence

The rapid detection method of brown tide algae concentration based on unthresholded recurrence plots and improved broad learning system

“…Meanwhile, EEM, which not only provides rich spectral information but also enables nondestructive detection of microalgal bioconcentrations, has been widely used in recent years [11][12][13]. However, this method requires presetting the initial excitation wavelength and emission wavelength, so there is still room for improvement in terms of rapidity LIFT has been widely used in biomedicine [14], environmental protection [15], and other fields because of its ease of operation and rapidity, and have been gradually introduced into the field of chemical analysis in recent years, for example Adarsh presented four methods including laser-induced fluorescence spectroscopy for the classification of plastics [16], Qiao et al proposed to extract phosphorus from aqueous solution using an iron-modified resin YZS60 and to detect phosphorus in combination with LIFS [17], Chen et al Proposed laser-induced fluorescence technique for data acquisition of olive oil, followed by classification using a specific onedimensional convolutional neural network (1D-CNN) mode [18]. As a result, LIFT enables efficient and non-destructive rapid detection of microalgae concentrations.…”
