a, b DL-reconstructed spectra (solid lines) with a step size of 0.5 nm (a) and 0.2 nm (b), respectively, and the measured spectra using a conventional spectrometer (spheres). The peak positions are indicated by vertical dashed lines [i.e., 605.0 nm (purple line), 605.5 nm (green line), and 606.0 nm (red line) in (a), and 605.2 nm (purple line), 605.4 nm (green line), and 605.6 nm (red line) in Fig. 3b]. c The spectra of the two incident light measured independently. d DL-reconstructed spectrum (solid lines) and the measured spectra of the two combined peaks using a conventional spectrometer (spheres).
