Abstract:
An optical arrangement for a head mounted display, having optical surface that can be described by standard mathematical equations. A prism element is used having three optical surfaces, and wherein the reference surface of the three optical surfaces are centered at, and have no tilt, relative to the optical axis. The prism has first surface that faces the display device and comprises a high order polynomial surface with a reference plane orthogonal to the optical axis. All of the surfaces of the prism are described by extended polynomials defined on a Cartesian coordinates having the z-axis coinciding with the optical axis.

Claim (Index 11):
An optical arrangement configured to be installed in an optical see-through head-mounted display defining an optical axis, comprising:\n a prism having:\n a first surface configured to receive light from a micro-display and configured to transmit the received light into the body of the prism; \n a second surface configured to receive the light transmitted into the body of the prism from the first surface and configured to totally internally reflect the received light at the second surface; and \n a third surface configured to receive the light reflected by the second surface and configured to reflect the light out of the prism towards a pupil of the head-mounted display; \n wherein each of the first, second and third optical surfaces is formed as high order extended polynomial, having reference plane that is centered with respect to the optical axis, and has no tilt with respect to the optical axis.
