摘要
色体视感被认为是眼横向色差(TCA)产生的结果,随瞳孔尺寸的改变,色体规感也发生变化。Einthoven的理论说明在小瞳孔条件下,TCA可以精确推测色体视感,但对于大瞳孔则不成立。Vos的理论认为SCE峰值位置与瞳孔不同心是色体视感随瞳孔变化而变化的原因。本文介绍了验证小瞳孔下Einthoven理论的合理性的实验,而在激光与适光(如适合人眼观察的通常照明条件)条件下的实验,证明SCE是影响色体视感的重要因素。
Chromostereopsis has been attributed to interocular differences in foveal trans-verse chromatic aberration (ThA ). Chromostereopsis changes as the pupil size changes.Einthoven's theory suggests that Chromostereopsis with small pupils can be precisely ac-counted for by the interocular difference in monocular transverse chromatic aberration,but itis not suitable with large pupils. Vos argues that shifts in Chromostereopsis with pupil sizeare due to decentration of the peak of the Stiles-Crawford effect (SCE)with respect to thepupil' This paper shows the experiment that tests the correction of Einthoven's theory andproves that SCE plays an importont role in the effect of pupil size on Chromostereopsis underboth scotopic and photopic conditions-
