包含眼睛单色像差的计算机模型用于确定轴向和横向分辨率的最佳瞳孔大小，因为它适用于共焦扫描激光检眼镜等视网膜成像仪器。轴向分辨率的最佳瞳孔大小。基于 15 名受试者的像差，标准偏差 (sd) 为 4.30 毫米 +/- 1.19 毫米，大于横向分辨率 [2.46 毫米 +/- 0.66 毫米 (sd)]。当使用小共焦针孔时，可在瞳孔尺寸为 4.90 mm +/- 1.04 mm sd 时获得最大检测光。建议在需要轴向分辨率的成像应用中使用较大的瞳孔尺寸。 (C) 2003 年美国光学学会。
A computer model that incorporates the monochromatic aberrations of the eye is used to determine the optimal pupil size for axial and lateral resolution as it applies to retinal imaging instruments such as the confocal scanning laser ophthalmoscope. The optimal pupil size for axial resolution,. based on the aberrations of 15 subjects, is 4.30 mm +/- 1.19 mm standard deviation (sd), which is larger than that for lateral resolution [2.46 mm +/- 0.66 mm (sd)]. When small confocal pinholes are used, the maximum detected light is obtained with a pupil size of 4.90 mm +/- 1.04 mm sd. It is recommended to use larger pupil sizes in imaging applications where axial resolution is desired. (C) 2003 Optical Society of America.
