Experimental study of the visual system using unidimensional Walsh gratings

Threshold characteristics of the visual system for an orderly set of the Walsh aperiodic gratings were estimated prior to and after adaptation. Narrow--band channels of Walsh with the band width about 1 octave by the Walsh scale of function orders, were revealed. The model of summation by the power of spectral sinusoidal components of the Walsh aperiodic lattices well accounts for the data on gratings the Walsh aperiodic gratings.
