Wearable optical see-through (ost) near-eye display (ned) system integrating ophthalmic correction with improved pantoscopic angle

Abstract

An optical see-through (OST) near-eye display (NED) off-axis system, providing ophthalmic correction to an eye of a user, for improving a pantoscopic angle in a system based on a glabellar region positioned electro-optical sub-system, the system includes a partially transmissive partially reflective lens, an intermediate reflective surface, and an electro-optical subsystem, the partially transmissive partially reflective lens includes a material having a refractive index, an inner surface characterized by an inner surface radius of curvature exhibiting a first optical power, and an outer surface characterized by an outer surface radius of curvature exhibiting a second optical power, said partially transmissive partially reflective lens is configured to be facing said eye, and to at least partially transmit incoming light of an outward scene to said eye, said intermediate reflective surface is characterized by an intermediate reflective radius of curvature exhibiting a third optical power, said intermediate reflective surface is embedded within said partially transmissive partially reflective lens, between said inner surface and said outer surface, said electro-optical sub-system is configured to be optically coupled with said partially transmissive partially reflective lens, said electro-optical sub-system including a light display configured to project a light beam image onto said intermediate reflective surface enabling reflection of said light beam image toward said eye, said electro-optical sub-system is configured to be located at a glabellar region of said user, wherein said first optical power and said second optical power are configured in conjunction with said material refractive index to provide ophthalmic correction with respect to transmitted said incoming light from said outward scene for viewing by said eye, wherein said third optical power is configured to provide ophthalmic correction with respect to reflected said light image for viewing by said eye, wherein said intermediate reflective surface is oriented such to have a tilt angle with respect to said at least one of said inner surface and said outer surface enabling a reduction of said pantoscopic angle.
