摘要： 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。

Abstract: This experiment was undertaken by using flicker method with 3 no-rmal vision experienced adult subjects. A white light and 3 spectral lights(670、560 and 450 nm) were used as stimulus lights; 4 visual feilds wereused about 2°、1°、0. 5°and 0. 25°; 3 levls of luminance were 200、20 and 2cd/m~2. The results indicate that 1) At any given luminosity level and withinthe same size of visual field, all CFF of green light turn out to be higherthan those of red and blue lights significantly. 2)Under the same lumino-us condition, CFF of both white light and various monochromatic lightsincrease as the visual field become larger. Furthermore, these changes tendto be linearly interrelated, that is to say, CFF increases with the logari-thim area of visual field nearly. 3)At various luminosity levels, slops oflines denoting CFF to log area of visual field varied, The slop at 2 cd/m~2is smaller than those of others.
