We demonstrate a compact optical phoroptor consisting of adjustable astigmatic and defocus lenses. The lenses are fluidically controlled and allow for an arbitrary refractive error to be corrected without mechanically moving lenses. Shack-Hartmann measurements were used to characterize the optical properties of the individual lenses. The lenses were then assembled into the phoropter and controlled with three separate fluid controls. The phoroptor was verified by correcting the vision of a model eye with an induced refraction error.
我们展示了一种由可调节的散光和散焦透镜组成的紧凑型光学检影镜。这些透镜通过流体控制，无需机械移动透镜即可矫正任意的屈光不正。利用 Shack-Hartmann 测量来对各个透镜的光学性能进行了特征描述。然后，将这些透镜组装到检影镜中，并通过三个独立的流体控制来进行控制。通过对具有诱导折射误差的模型眼进行视力矫正，验证了检影镜的性能。
