TILT PERCEPTION INDUCED BY DIFFREQUENCY IN DIFFERENT VISUAL CHANNELS
不同视觉通道中频差所引起的深度感知

It was tested that if the stereoscopic tilt effect can be induced by binocular diffrequency in the diffrerent spatial frequency channels. Two sets of psychophysical experiments were conducted. The tilt effect induced by binocular diffrequency in the second and the fourth peaks of Wilson's modulated curve (1.7cpd and 4.0cpd ) have been observed and the equal tilt perception have the same diffrequency ratio (diffrequency divided by the central frequency in that band ). Within a certain extent of diffrequency ratio (0.70-1.30), the perceived tilt effect was proportional to the diffrequency ratio.
