    Abstract: 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.

    Abstract: A wavefront sensor includes a light source configured to illuminate a subject eye, a detector, a first beam deflecting element configured to intercept a wavefront beam returned from a subject eye when the subject eye is illuminated by the light source and configured to direct a portion of the wavefront from the subject eye through an aperture toward the detector and a controller, coupled to the light source and the beam deflecting element, configured to control the beam deflecting element to deflect and project different portions of an annular ring portion of the wavefront from the subject eye through the aperture and further configured to pulse the light source at a firing rate to sample selected portions of the annular ring at the detector.

    Abstract: One embodiment disclosed is a compact wavefront sensor module to be attached to or integrated with an ophthalmic instrument for eye examination and/or vision correction procedures. The front lens for relaying the wavefront from the eye to a wavefront sampling plane is positioned at the optical input port of the wavefront sensor module. The front lens is shared by the wavefront sensor and the ophthalmic instrument, and the wavefront sensor module can be made very compact while still being able to cover a large eye wavefront measurement diopter range. Another embodiment disclosed is an ophthalmic device for measuring properties of a subject eye including an ophthalmic instrument integrated with the wavefront sensor module.
