Example embodiments of a large dynamic range sequential wavefront sensor for vision correction or assessment procedures are disclosed. An example embodiment optically relays a wavefront from an eye pupil or corneal plane to a wavefront sampling plane in such a manner that somewhere in the relaying process, the wavefront beam from the eye within a large eye diopter range is made to reside within a desired physical dimension over a certain axial distance range in a wavefront image space and/or a Fourier transform space. As a result, a wavefront beam shifting device can be disposed there to fully intercept and hence shift the whole beam to transversely shift the relayed wavefront.本發明揭示用於視力校正或評估程序之一大動態範圍連續波前感測器之實例性實施例。一實例性實施例以使得在中繼過程中之某處使一大的眼睛屈光度範圍內之來自眼睛之波前光束在一波前影像空間及/或一傅立葉變換空間中駐留於一特定軸向距離範圍內之一所期望實體尺寸內之一方式將一波前自一眼睛瞳孔或角膜平面光學中繼至一波前取樣平面。因此,一波前光束移位裝置可安置於彼處以完全截取且因此移位整個光束以橫向移位該經中繼波前。204‧‧‧第一透鏡212‧‧‧透射式光學光束掃描器或位移器/透射式光學光束掃描器/透射式光束掃描器216‧‧‧第二透鏡A‧‧‧傅立葉變換平面/第一傅立葉變換平面B‧‧‧經中繼波前影像平面/波前影像平面/波前中繼平面/波前中繼影像平面/平面/第一波前影像平面/第一經中繼波前影像平面
