高放大率视网膜成像的最新进展已经允许个体视网膜光感受器的可视化，但是这些系统也遭受由于固定眼睛运动而引起的失真。为消除这些失真而开发的算法具有额外的好处，即提供产生这些失真的眼睛运动的弧秒级分辨率。该系统还允许视网膜上的目标的可视化，允许绝对视网膜位置测量到各个视锥的水平。本文将描述用于去除眼动伪影的过程，并对其光谱特性进行分析。我们发现了一个近似1/f的振幅谱，类似于Findlay（1971）报道的振幅谱，没有明显的震颤分量的证据。
Recent advances in high magnification retinal imaging have allowed for visualization of individual retinal photoreceptors, but these systems also suffer from distortions due to fixational eye motion. Algorithms developed to remove these distortions have the added benefit of providing arc second level resolution of the eye movements that produce them. The system also allows for visualization of targets on the retina, allowing for absolute retinal position measures to the level of individual cones. This paper will describe the process used to remove the eye movement artifacts and present analysis of their spectral characteristics. We find a roughly 1/f amplitude spectrum similar to that reported by Findlay (1971) with no evidence for a distinct tremor component.
