实验探究费希纳颜色效应

Experimental study of Fechner color effect

费希纳颜色效应是一个很知名的视觉现象,是指转动分布着黑白相间条纹的圆盘(贝汉转盘)能够看到彩色环的现象,它的形成原因目前仍未有定论.本文对费希纳颜色效应进行了实验探究,在对贝汉转盘进行改进的基础上,从光源、转速、条纹宽度等方面着手,对费希纳颜色效应的现象和规律进行了量化研究,对其成因进行了适当推测.

The Fechner color effect is a well-known visual phenomenon. When one sees a rotating turntable which with some black and white patterns on it such as Benham＇s top, one will see several other colors. The cause of its forma- tion is still inconclusive. We analyze the phenomenon, improve the Benham＇s top, and make some experiments. Quantita- tive experiments are performed on aspects of the light source, rotational speed, stripe width and so on.
