The Modulation Transfer Function of the human visual system has been determined with a sin usoidal test target, by measuring the threshold contrast as a function of spatial frequency, for monochromatic light of constant average luminace. Data were obtained for a broad band range and wavelengths of 538 and 617 nm. It is shown that a maximum MTF occurs at frequencies between 2 0 - 3 0 cycles/mm on the retina and that this sensitivity decreases for both lower and higher frequencies. Small but discrete differences appear in the curves for broad-band radiation and the green and red filtration at the photopic luminances.
