Joel S Kollin, Richard S Johnston, Charles D Melville: Virtual retinal display with expanded exit pupil. University of Washington, Steven P Koda Esq, December 23, 1997: US05701132 (131 worldwide citation)

A display device is achieved using a simplified optical system which generates an expanded exit pupil without compromising magnification or resolution. Modulated light from a source is converged toward a focal point by an optics subsystem. A scanning subsystem deflects the converging light, and thus ...
