A diffractive optic reflex sight (DORS) is provided for aiming devices in which a virtual image, such as a reticle, is produced and appears in the distance of a user's view when looking through the reflex sight. A light source illuminates a diffractive optical element (DOE) that includes a modulation pattern that generates a patterned illuminations corresponding with the virtual image. A reflective image combiner then reflects the patterned illumination so that the virtual image appears in the distance of the viewer's view. The DORS optical design system is mechanically and optically stable for precision aiming across a range of environmental conditions and in different use scenarios or applications including use in rapidly changing temperatures, varying light conditions, and a wide range of user proficiencies. The DORS optical design system is a readily manufacturable aiming and sighting device for a wide range of applications from handguns to astronomical telescopes.

An extended field-of-view near-to-eye display system provides for AR/MR image viewing over about a 180° FOV. The display system may include a multiplicity of display panels per eye of a user and may include both high- and low-resolution display capabilities. The high-resolution displays may be positioned in front of the user's eyes in their primary visual field while the low-resolution displays may be positioned so as to be seen by the user's peripheral vision. The low-resolution displays provide cueing information to the user out to the limit of visual perception (for each eye), placing encoded light and movement in the periphery of the user's vision for enhanced situational awareness.

The direct view optic may include an optical device having a front objective, a rear ocular exit, and a waveguide.

A sight or aiming device is provided that can be attached to a firearm or other device with minimal visual and weight impacts and includes a light source, a pattern producing element, and an imageguide optical combiner. The user may have access to mechanical adjustments to “zero” the sight to the barrel of the instrument and to correct an aim point for windage and elevation. The orientation and construction of the sight facilitates use with a holster. The sight has an on-axis (or in-line) optical design, and thus the illumination of a reticle by the light source and its path entering the on-axis imageguide holographic combiner is approximately parallel to the boresight of the instrument that the sight is attached to.
An optical system for displaying light from a scene includes an active optical component that includes a first plurality of light directing apertures, an optical detector, a processor, a display, and a second plurality of light directing apertures.
