The vertical missing fundamental (mf) gratings used to explore horizontal disparity vergence. A: x-y plot of the luminance, showing the two vertical grating patterns as seen by the left (LE) and right eyes (RE) when presented with a ¼-wavelength phase difference that has crossed disparity. B, C: the luminance profiles of the mf stimuli seen in A are shown here in grey line, with the 3rd harmonics (in B) and the 5th harmonics (in C) superimposed in black line. The ¼-wavelength phase differences of the 3rd harmonic (uncrossed disparity) and of the 5th harmonic (crossed disparity) are indicated in dashed line.
