Abstract:
1. Alignment correction system for a direct-viewing optical device, comprising: one or more corrective optical elements optically incorporated with the direct-viewing optical device, wherein the corrective optical elements include customized optical parameters applicable to ameliorate one or more aberrations of a particular user, the direct-viewing optical device comprising one or more of a microscope, a telescope, binoculars, a weapon sight, a gun sight, a diagnostic tool, a manufacturing inspection device, a hand-held device, a head mounted device, and a body mounted device; a sensor adapted to track a gaze direction of the particular user during a period of optical device usage by the particular user; a sensor adapted to indicate an aperture stop or a focal length of the direct-viewing optical device for respective fields of view in different gaze directions as a basis for dynamically repositioning the corrective optical elements; and a control module operatively connected to the sensor and configured to implement a mode comprising dynamic repositioning of the corrective optical elements in order to produce a specified change in optical wavefront at an exit pupil of the direct-viewing optical device, based upon the tracked gaze direction of the particular user and the aperture stop or the focal length of the direct-viewing optical device, wherein the tracked gaze direction comprises an angle of the eye with respect to the direct-viewing optical device, and wherein said control module is configured to implement a first operational mode causing real-time physical repositioning of the corrective optical elements in response to a detected shift of the tracked gaze direction, wherein the physical repositioning comprises one or more of translational and rotational physical realignment of the corrective optical elements to cause a central viewing axis of one or more of the corrective optical elements to be substantially parallel with the tracked gaze direction.
