摘要

在这个手稿中，我们提出了一个镜头设置大散焦和散光校正。采用可变形离焦透镜和两个旋转圆柱透镜控制离焦和像散。该装置使用一个简单的模型进行校准，该模型允许计算透镜输入，以便在眼睛上驱动所需的散焦和散光。通过确定前馈预测误差，成像分辨率目标和去除引入的像差来测试该设置。

Feedforward operation of a lens setup for large defocus and astigmatism correction

In this manuscript, we present a lens setup for large defocus and astigmatism correction. A deformable defocus lens and two rotational cylindrical lenses are used to control the defocus and astigmatism. The setup is calibrated using a simple model that allows the calculation of the lens inputs so that a desired defocus and astigmatism are actuated on the eye. The setup is tested by determining the feedforward prediction error, imaging a resolution target, and removing introduced aberrations.
