本实验采用闪烁光度法。刺激光为红光(670nm)、绿光(560nm)、蓝光(450nm)和白光。亮度级为200尼特、20尼特和2尼特。视场约为2°、1°、0.5°和0.25°。受试者3人,均属色觉正常者,具有一定实验经验。结果表明:在同一亮度级上,大小相同的视场内,绿光的CFF都明显地高于明度相同的红光和蓝光的CFF;在同一亮度级上,色光和白光的CFF都随着视场面积的增加而增加。并且CFF-Log面积接近线性关系;在不同亮度级上,CFF-Log面积的直线料率并不相同。2尼特时的直线斜率小于20尼特、200尼特时的直线斜率。
The experiment used flicker spectrophotometry. Stimulus light is red (670 nm), green (560 nm), blue (450 nm), and white. Brightness levels are 200 nits, 20 nits and 2 nits. The field of view is approximately 2 °, 1 °, 0.5 ° and 0.25 °. Subjects 3, are normal color vision, with some experimental experience. The results show that at the same brightness level, the CFFs of the green light in the same field of view are obviously higher than those of the red and blue lights with the same brightness; in the same brightness level, The increase of field area increases. And the CFF-Log area is close to a linear relationship; at different brightness levels, the linear feed rates of CFF-Log area are not the same. 2 nits straight line slope less than 20 nits, 200 nits straight line when the slope.
