US Army awards DigiLens, Inc.® $450,000 Extension to Large Area Collimated Display Contract

SUNNYVALE, CA – Jan. 14, 2014: DigiLens in partnership with Rockwell Collins, has received a funds extension on a March 2013 contract from the Army’s Night Vision Laboratory, supporting further development of a next generation display to work with the Army’s Driver Vision Enhancement (DVE) program. The two-part contract calls for the development of a monochrome collimated display followed by a full color display.

Drivers in vehicles like the Abrams tank look at a small (15in) monitor for night vision assisted driving operation. In this non-collimated display, drivers can experience discomfort or nausea while looking at this display, especially in a moving vehicle.

A collimated display, or virtual window, addresses this issue with a displayed image stabilized with respect to the observer. Distant objects remain fixed in space as the head moves, just as they do when one looks out a window. Replacing the existing DVE display with a collimated display will significantly reduce or eliminate viewer discomfort and nausea.

In phase one of this contract, DigiLens will demonstrate a large (8 inch) diagonal, monochrome, green collimated display using its proprietary Switchable Bragg Grating (SBG) technology. A display with a limited field of view will be used to prove out the feasibility before a color display with a wider field of view is constructed. This SBG technology has been proven in smaller sized display, but this will be the first time it has been used in such a large display surface. It is also the first time that a display will be viewed at arm’s length instead of near the eye, which allows viewers to focus on the display surface.

DigiLens uses holographic exposure tools to create electrically switchable optical gratings and diffractive optical elements that can be embedded in the thin (2mm) clear optical waveguides. This allows an image to be injected into the waveguide from the side where it travels down the waveguide by total internal reflection. These switchable elements are used to extract the image with the ability to increase the resolution and/or field of view of the image.

“Collimated displays are typically associated with large aircraft simulators using projection systems with complex screen technology,” said DigiLens CTO Jonathan Waldern. “This is the first time, we are aware of, a collimated display will be made in this size and thinness–and certainly the first to do this in a planar waveguide using holographic technology.”
