本实验用APPLE Ⅱ微机控制的同视机,选用医用三级检查图片中的彩色和黑白两种立体图对,对30名被试进行实验。结果表明:(1)在同视机条件下,当双眼图象交替闪烁相位的交替频率平均在7Hz以上时,双眼立体视觉形成。(2)双眼刺激交替呈现时,彩色图对的立体感闪烁融合阈值约为33Hz,黑白图对的立体感闪烁融合阈值约为25Hz,两者差异十分显著(P<0.0001)。
The experiment with APPLE Ⅱ microcomputer control with the same machine, the selection of three medical examination pictures of color and black and white two pairs of stereo pairs, 30 subjects were tested. The results show that: (1) Under the condition of the same seeing and hearing machine, the binocular stereoscopic vision is formed when the alternating frequency of the alternate scintillation phases of the two eyes images is above 7 Hz on average. (2) When the two eyes are stimulated alternately, the threshold of three-dimensional scintigraphy of color pairs is about 33Hz, and the threshold of three-dimensional scintigraphy of black and white pairs is about 25Hz, the difference is significant (P <0.0001).
