    摘要： The present invention provides a wide-filed spectral imaging system including a laser generator, a wavelength adjustment module, an objective lens, and a single-pixel imaging and a spectral separating module. The laser generator is configured to generate a laser excitation beam. The wavelength adjustment module is configured to disperse the laser excitation beam into a plurality of beams of different wavelengths. The objective lens is configured to focus the plurality of beams of different wavelengths on a sample to excite molecules under test in the sample and generate an emission light. The single-pixel imaging and spectral separating module is configured to generate a series of patterns and modulate the emission light with the series of patterns to generate a diffracted beam. The single-pixel imaging and spectral separating module further disperses the wavelength of the diffracted beam, collects light signals of the expanded diffracted beam, and performs a spectral image reconstruction.

    摘要： A hyperspectral imaging device and method disclosed herein overcomes the technical problems associated with the prior art by replacing the intensity measurement performed by the single high-resolution 2D sensor of state-of-the-art methodologies, with the measurement of intensity (fluctuation) correlations retrieved by two high-resolution 2D sensors: one—the imaging/spatial sensor dedicated to polychromatic image acquisition, the other—the spectral sensor dedicated to pure spectral measurement. In the hyperspectral correlation imaging disclosed herein, the spectral information is encoded into the intensity correlation without requiring any spectral scanning. Even though multiple exposures (frames) are generally required to reconstruct light statistics and perform correlation measurements, the exposure times are several orders of magnitude shorter than those required in the scanning approach. In addition, no changes of the device are required during such multiple exposures, which simplifies the optics/optomechanics of the device and avoids further time consumption.
