WebOct 1, 1997 · Stereoacuity was determined for gratings and gabor patches as their orientation was varied. Acuity was constant for 1 c/deg and 2 c/deg gratings over the range 0–80 deg when it was expressed as positional shift at right angles to the grating orientation. The same was true of an 8 c/deg elongated gabor patch.

In the wave grating formed by a sinusoid function, the image’s light intensity alternates between its darkest and brightest according to this function. If no envelope is applied, there would be sharp edges where the grating and the background meet.
