Abstract
Official abstract text for this publication.
Exemplary methods, systems and components enable an enhanced direct-viewing optical device to include customized adjustments that accommodate various optical aberrations of a current user. A real-time adjustment of transformable optical elements is sometimes based on predetermined corrective optical parameters associated with a current user. Customized optical elements are incorporated with the direct-viewing optical device to produce a specified change in optical wavefront at an exit pupil. Possible transformable or replacement optical elements may have refractive and/or reflective and/or diffractive and/or transmissive characteristics that are selected based on current performance viewing factors for a given field of view of the direct-viewing device. Some embodiments enable dynamic repositioning and/or transformation of corrective optical elements responsive to a detected shift of a tracked gaze direction of a current user. Replacement corrective optical elements may be fabricated for current usage or retained in inventory for possible future usage in the direct-viewing device.
First claim
Opening claim text (preview).
The invention claimed is: 1. A customized optical system for a direct-viewing optical device, comprising: one or more transformable optical elements incorporated in the direct-viewing optical device; a control module operatively coupled to the transformable optical elements in a manner to selectively transform the transformable optical elements to produce a specified wavefront change applicable to a current user at an exit pupil of the direct-viewing optical device; a user-int…
