%X In order to study the effect of different complexities of depth patterns on stereopsis a psychophysical experiment with Random Dot Stereogram (RDS) was conducted. A set of static RDS with different frequencies of sinusoidal variation in disparity, which designated the complexity of pattern, was used to study binocular stereopsis. The result defined a region within certain frequencies of sinusoidal variation of disparity, at which depth could be seen. The range of frequency of sinusoidal variation in disparity was from 0. 1 to 4 (cycle per degree) at the region. The high frequency limitation of depth perception was at 4 cycles per degree. So stereopsis was a function of the complexity of depth pattern. There were some differences of binocular disparity sensitivity in the seven subjects, but the shapes of these seven regions were similar.
