Area MTF as a function of accommodation distance for a two-plane display. The model eye is diffraction limited with a 4mm pupil. The stimulus is monochromatic (550nm) and contains all spatial frequencies at equal contrast from 0 to 30 cpd. The planes are positioned at 0 and 0.6 D (indicated by arrows). MTF area was calculated from 0 to 30cpd for intensity ratios of 0.5, 0.25, and 0.
