An optical assembly comprises a light source, a light-modulation element for modulating light from the light source, and a terminal optical element for directing modulated light from the optical assembly. Optical elements are provided to guide the light in a first path from the light source to the light-modulation element and to guide the modulated light in a second path from the light-modulation element to the terminal optical element. The first and second paths are of similar shape, for example a c-shape, and are arranged in a nested configuration.

An ocular optical system includes a light guiding prism that guides image light from a display element and an emission portion that emits the image light guided by the light guiding prism. The light guiding prism includes a plurality of sides arranged to surround a light path of the image light, and a reflection surface off which the image light is reflected to the emission portion. The plurality of sides include a first side that is arranged on an opposite side of a first plane including first and second optical axes and that is situated between the emission portion and the reflection surface, wherein the first optical axis is a portion of the image light before the image light is reflected off the reflection surface, and the second optical axis is a portion of the image light after the image light is reflected off the reflection surface.

Various embodiments of the present invention provide systems, methods, and processes for constructing a contact lens. In one embodiment, a contact lens assembly is provided, comprising: a curved polymer polarizer with an aperture; a lenslet disposed inside the aperture, wherein the lenslet enables imaging near objects; and a filter attached to the lenslet. In further embodiments, a method for fabricating a flexible contact lens is provided, comprising: fabricating an element having an extrusion; providing a front concave mold, wherein the front mold has an intrusion to accommodate the extrusion of the optical element; affixing the extrusion of the optical element to the intrusion of the front mold; attaching a back convex mold to the front concave mold, thereby forming a mold cavity; and filling the mold cavity with a pre-polymerized liquid, whereby upon polymerization, the pre-polymerized liquid forms the flexible contact lens and the optical element is partially encapsulated within the lens.

The present invention comprises a compact optical see-through head-mounted display capable of combining, a see-through image path with a virtual image path such that the opaqueness of the see-through image path can be modulated and the virtual image occludes parts of the see-through image and vice versa.

An image generation unit includes a display panel, a first illumination system, and a second illumination system. The display panel has a first and a second imaging regions adjacently arranged and located on the same plane. The first illumination system provides a first light beam incident on the first imaging region at a first incident angle. The first imaging region converts the first light beam into a first image beam. The second illumination system provides a second light beam incident on the second imaging region at a second incident angle. The second imaging region converts the second light beam into a second image beam. The optical paths of the first light beam and the second light beam do not intersect with each other. The first image beam and the second image beam leave the display panel at different light exit angles.
