Austin John Roorda

US Patent:

7118216, Oct 10, 2006

Filed:

May 10, 2005

Appl. No.:

11/125331

Inventors:

Austin Roorda - Houston TX, US

Assignee:

University of Rochester - Rochester NY

International Classification:

A61B 3/00
A61B 3/10
G02B 26/08

US Classification:

351205, 351221, 351246, 359202

Abstract:

A scanning laser ophthalmoscope incorporates adaptive optics to compensate for wavefront aberrations in the eye. Light from a light source is scanned onto the retina. Light reflected from the retina is detected for imaging and is also used for wavefront sensing. The sensed wavefront aberrations are used to control an adaptive optic device, such as a deformable mirror, disposed in the path of the light from the source in order to compensate for the aberrations.

Abstract:

According to various embodiments of the invention, systems and methods for stimulating the retina are presented, by a combination of some or all of the following: imaging and mapping the retina; determining or assigning parameters on the retinal map, including real and virtual cell types and properties; tracking the head and/or eye; receiving or creating, transforming and/or projecting desired image signal onto the retinal map; combining the desired image with retinal parameter map data in order to determine per-cell or per-retinal-location stimulus values; and delivering the desired stimulus values to the retina. According to various embodiments of the invention, improved or novel color display, vision and perception are achieved: color gamut that encompasses the full human gamut; gamut that goes beyond the full human gamut; providing trichromatic vision functionality and/or color perception to dichromats, monochromats and/or individuals with anomalous color vision; providing perception of N-dimensional color, where N is higher than 3.
