Simulations of the appearance of the TCA stimulus as a function of pupil position. A) Model wavefront of a typical eye used for simulations. Units for the color bar are micrometers. Colored circles overlaid on the wavefront image demarcate the area of the pupil which was sampled to generate the PSFs shown in B). Defocus was set to zero for the centered position only (yellow circle). The pupil offsets for each sample relative to the centered position are given in millimeters (mm) along the margins of panels B) and C). C) Simulations of the appearance of the stimulus, generated by convolving the PSFs shown in B) with the aligned stimulus (Fig. 1A). Each image represents the stimulus appearance at a different vertical or horizontal pupil offset (units are mm). Note that this does not include the offset between stimuli incurred by chromatic aberration, and thus is representative only of the appearance with monochromatic blur.
