Abstract:
Disclosed herein are systems and methods of reducing distortion in an image displayed on a near-eye display. Described herein is a display system including a light assembly configured to generate source light for a display image, a distortion correcting optics assembly, and a mirror scanning system configured to receive pre-distorted and collimated light and reflect and scan the pre-distorted and collimated light to provide an image on an image plane. The distortion correcting optics assembly delivers pre-distorted and collimated light to the mirror scanning system, the mirror scanning system is configured to undistort the pre-distorted light and transmit an undistorted image to a display.
