我们已经开发了一种成像反射仪来测量锥光感受器对齐。人们通过漂白视锥色素并对从视网膜返回的光的分布成像来进行测量，视网膜是从眼睛瞳孔平面中成像的小光源照射的。如果光源接近心理学确定的最佳入射瞳孔位置，则从视网膜返回的光的分布达到峰值，并且峰值的幅度取决于光源在瞳孔中的位置。的眼睛。如果源远离最佳入射光瞳位置，则不存在可测量的峰值。峰值的位置因个体而异，并且与测量光的最佳可见度的报告位置以及先前对Stiles-Crawford峰值的心理物理和反射测量相一致。这种方向性的来源必须来自光感受器或来自光感受器的后面，因为如果在视锥细胞色素具有高光密度时进行测量，则不存在峰。
We have developed an imaging reflectometer to measure cone-photoreceptor alignment. One makes measurements by bleaching the cone photopigment and imaging the distribution of light returning from the retina, which is illuminated from a small source imaged in the plane df the eye's pupil. If the source is near the optimal entry pupil position as determined psychophysically, the distribution of light returning from the retina is peaked, and the magnitude of the peak depends on the location of the source in the pupil. of the eye. If the source is far from the optimal entry pupil position, then there is no measurable peak. The location of the peak varies across individuals and coincides with the reported location of best visibility of the measuring light and with previous psychophysical and reflectometric measurements of the Stiles-Crawford peak. The source of this directionality must arise either from the photoreceptors or from behind the photoreceptors because the peak is not present if measurements are made when the cone photopigments have high optical density.
