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 19):
A method for forming optical elements for a head mounted display (HMD) comprising:\n defining an optical axis as a straight line from a pupil of the HMD to an aperture of the HMD; fabricating a prism by forming a first surface configured to face a micro-display installed in the HMD, the forming of the first surface is performed by defining the surface form of the first surface by a high order expanded polynomial having an origin centered on the optical axis and a z-axis coinciding with the optical axis; forming a second surface configured to face the pupil, the forming of the second surface is performed by defining the surface form of the second surface by a high order expanded polynomial having an origin centered on the optical axis and a z-axis coinciding with the optical axis; and forming a third surface configured to face the aperture, the forming of the third surface is performed by defining the surface form of the third surface by a high order expanded polynomial having an origin centered on the optical axis and a z-axis coinciding with the optical axis.
