Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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. The first plurality of light directing apertures is positioned to provide an optical input to the optical detector. The optical detector is positioned to receive the optical input and convert the optical input to an electrical signal corresponding to intensity and location data. The processor is connected to receive the data from the optical detector and process the data for the display. The second plurality of light directing apertures is positioned to provide an optical output from the display.
