采用阈值法探讨了人眼在红、橙、绿、蓝4种色光适应条件下红、绿光感受性的变化及机制。结果表明:当背景及目标均为稳光时,在不同的背景光条件下,人眼554nm(绿)及656nm(红)光感受性的变化显示了明显的感觉颉抗性效应,且不受色觉适应的影响;如果所呈现的背景光是稳态光,目标先是闪烁光,除辨别是现在554nm背景光上的656nm(红)目标,在其余条件下,均未发现颜色感觉颉抗效应;如果背景光是闪烁光,目标光为稳态光时,在不同的背景光条件下,人眼对554nm(绿)及656nm(红)波长的辨别结果有感觉颉抗效应存在,并且辨别感受性也明显提高。
Threshold method was used to investigate the change and mechanism of the red and green sensitivities of human eyes under the conditions of four kinds of shades of red, orange, green and blue. The results show that under the different background light conditions, the changes of the human light sensitivity of 554nm (green) and 656nm (red) light show obvious sensory antagonistic effects when the background and the target are stable, and are not affected by the color sense Adaptation; if the presented background light is steady-state light, the target is first flashing light, except for identifying the 656 nm (red) target on the current 554 nm background light, and no color sense anti-antagonistic effect is found under the remaining conditions; if When the background light is a blinking light and the target light is steady-state light, the human eye perceives the anti-interference effect at the wavelengths of 554 nm (green) and 656 nm (red) under different background light conditions, and the distinguishing sensitivity is also obvious improve.
