随机点技术被用来研究人类视觉系统对运动视差信息所指定的正弦深度调制的敏感性。当深度波纹的空间频率在0.2 ~ 0.5c/度视角之间时，深度知觉的阈值最小。这些数据进行了比较，使用类似的设备和心理物理程序的双眼视差指定的感知深度皱纹的等效阈值。灵敏度函数之间的相似性暗示了两个系统之间的关系比以前认为的更密切。
Random dot techniques were used to investigate the human visual system''s sensitivity to sinusoidal depth modulations specified by motion parallax information. Thresholds for perceiving depth were smallest when the spatial frequency of the depth corrugations was between 0.2 and 0.5 c/degree visual angle. These data were compared with the equivalent thresholds for perceiving depth corrugations specified by binocular disparity using similar apparatus and psychophysical procedures. The similarity between the sensitivity functions is suggestive of a closer relationship between the 2 systems than previously thought.
