Abstract: A random grating based compressive sensing wideband hyperspectral imaging system comprising a front imaging component, an optical splitting component, more than two branches, and a computer, with each branch having an exit pupil transformation component and a compressive spectral imaging component. The system is based on compressive sensing theory, makes use of the correlation between spectra, increases compression rate on the spectral dimension, realizes three-dimensional compressive collection of wideband spectral image data, and greatly reduces data collection amount. The system is capable of measuring spectral image information on a wideband spectrum with a single exposure, and may obtain high spatial resolution and high spectral resolution by means of designing the random gratings on the various spitting paths.

Abstract: An analysis apparatus includes a plasma generation unit and an optical analysis unit. The plasma generation unit generates initial plasma by momentarily energizing a target substance to be turned into a plasma state, and maintains the target substance in the plasma state by irradiating the initial plasma with an electromagnetic wave for a predetermined period of time. The optical analysis unit identifies the target substance based on information with respect to emission intensity during a period from when the emission intensity reaches a peak due to the initial plasma until when the emission intensity increases and reaches approximately a constant value due to electromagnetic wave plasma maintained by the electromagnetic wave, or information with respect to emission intensity after the electromagnetic wave irradiation is terminated.
