a Testing results for single-peak spectrum inputs: (i–iii) the peak wavelengths of input single-peak spectra are ~450, ~550, and ~650 nm, respectively. b Testing results for dual-peak spectrum inputs: (i, ii) the wavelength separations of input dual-peak spectra are 0.8, and 1.0 nm, respectively. c The root-mean-square errors (RMSEs) of the peak wavelengths of the reconstructed spectra for narrow single-peak spectrum inputs. d The FWHMs of the reconstructed spectra for narrow single-peak spectrum inputs. e Testing results for some broadband input spectra: (i–iv) the bandwidths of the broadband input spectra are ~85, ~40, ~37, and ~22 nm, respectively.
