ABSTRACT:
A pattern ERG (PERG) projector includes a coherent light source (32) for generating a projection beam, modulation optics (34) for modulating the projection beam with an alternating ERG interference pattern with a selected spatial and alternation frequency, and wide angle imaging optics (36) for focusing the projection beam such that it passes through the pupil, and then diverges to project onto a selected portion of the retina.
