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 retlex 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.
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.
A protective facemask includes a holographic display system and particularly holographic image guides (hereinafter "HID") to relay display content into the user's field of view from a display engine while disturbing as little of the field of view ("FOV") as possible with display hardware. In certain embodiments (or as desired), the holographic image guides can provide a daylight and night readable images with a 25Vx40H field of view, 60fps framerate, contrast >1000:1, 720p resolution and full color. In addition, or as an alternative to the holographic image guides, certain embodiments of the facemask do not contain a standard nose cup, but instead contain equalization features that allow the user to equalize the pressure within the eye wells and prevent harm to the user. In certain embodiments, a facemask includes a self-adjusting pressure system.

A direct enhanced view optic (DEVO) provides a user with enhanced target acquisition information, such as real time ballistic solutions, fused thermal imaging, extended zoom, and automatic target recognition. The direct view optic may include an optical device having a front objective, a rear ocular exit, and a waveguide. The front objective and the rear ocular exit may be separated by the waveguide, and the optical device provides a distant image onto a display. A diffractive based holographic display system is coupled to the optical device, and the holographic display system provides a see-through information overlay on the display.
A display system with a holographic image guide provides an integrated display for optical devices that allows augmenting information to be overlaid on a user's field of view. The display system has a reduced form factor that allows the display to ergonomically integrate into existing and future optical devices, such as glasses, helmets, masks, and goggles. The holographic display system can be used behind other optical enhancement devices, such as night vision goggles. The display system is relatively lightweight and can provide sufficient visible light intensities (e.g., 14,000 nits) so that the augmenting information is readable when the scene viewed by the user is in bright sunlight. Variable intensity control also allows the augmenting information to be displayed and viewed in a wide range of other conditions, including low light, night vision, underwater, and low visibility.

Light-based deciphering and transmission of information from one remote party to another in line-of-sight is disclosed. The system speeds the pace of light-based transmissions, the decoding of transmissions, and improves the accuracy of reception of the transmissions. In certain embodiments, the system sends both visual and infrared light to send different types of information to the recipient or to send information under different conditions. Exemplary embodiments disclosed herein demonstrate three exemplary systems (mechanical, LCD, and LED) that are suitable for combination with the other components of the system as disclosed herein. In certain embodiments, the system is configured to focus on the correct light (when there are other lights in view) sending the code (e.g., Morse code or On-Off Keying) and track it.
