【摘要】 为研究同时颜色对比机制的空间特性,本实验用光学投影方法产生出不同空间频率的同时颜色对比光栅。实验结果表明,同时颜色对比机制具有低通空间频率反应特性,即随空间频率下降,颜色对比效应增强。这一结果可能为同时颜色对比机制参与图形探测的推论提供一个实验支持。实验中也测试了几种不同条件下人眼对比敏感度函数。更多还原

【Abstract】 Simultaneous color contrast gratings with different spatial frequencywere optically generated to examine the spatial property of the simulta-neous color contrast mechanism. Results show that the simultaneous col-or contrast mechanism display low pass spatial frequency characteristics,becoming relatively more effective as the spatial frequency decreases. Th-ese results may provide an experimental support for the suggestion that si-multaneous color contrast mechanism takes part in pattern detection. Thecolor contrast sensitivity functions at different stimulation conditions arealso investigated in this experiment.更多还原
