Spectral sensitivities (normalized responsivity spectra) of human cone cells, S, M, and L types. 1916 plot of spectral sensibilities.. The author also uses the more modern term spectral sensitivity in the same book. Spectral sensitivity is the relative efficiency of detection, of light or other signal, as a function of the frequency or wavelength of the signal.
