a Broadband and b narrowband spectral reconstruction using the integrated spectrometer. The broadband spectrum is generated by a continuous laser while the narrowband spectra are generated by the PL from QD film with different nanocrystal sizes. Results show that the integrated spectrometer is capable of precisely reconstructing input spectra. c Schematic measurement setup of the hyperspectral imaging. d Reconstructed RGB image and e spectral information of the two areas within. Results show that the integrated spectrometer can be used in hyperspectral imaging that resolves the spatial and spectral information
