The head-up display 114 in FIGS. 10-11 and 14-15 is preferably an electroluminescent display although it may also comprise a liquid crystal display (LCD). In this regard, reference is made to U.S. Pat. No. 5,254,852, the entire contents of which are incorporated herein by reference, which describes the use of a liquid crystal display device for presenting a secondary image to a user in a night imaging system.
I believe there is only 1 microdisplay in these units -
The head-up display shown in FIGS. 27 and 28 is commonly referred to as AMELD (active matrix ectroluminescent display), although it may also comprise a liquid crystal display (LCD). In this regard, reference is made to U.S. Pat. No. 5,254,852, the entire contents of which are incorporated herein by reference, which describes the use of a liquid crystal display device for presenting a secondary image to a user in a night imaging system. In general, the information presented on the electronic display is selected and formatted in a computer and is presented to the display subsystem as a nominal RS-170 or the like monochrome, on-off (no gray scale or with gray scale type) visor-mounted panoramic night vision apparatus 50 of FIGS. 10-15 are described in detail in U.S. Pat. No. 5,416,315, the disclosure of such patent is hereby incorporated herein by reference.
The display 150 may be constructed using any technology capable of displaying a sufficient number of pixels or subpixels to produce a high resolution, wide field of view image. Examples of display technology that may be used include liquid crystal displays (LCD), liquid crystal on silicon (LCOS) displays, plasma displays, light emitting diode (LED) displays, or organic light emitting diode (OLED) displays.
The F-Pano also incorporates a high-resolution display and an embedded wireless personal area network that uses augmented reality algorithms to interface with the operator’s end-user device. The complete system facilitates a hyper-enabled operator with the ability to interface with multiple sensors throughout the battlespace, providing enhanced interoperability and data sharing.
The Fused GPNVG (F-Pano) solution, which also features four image intensification (I2) tubes, has been enhanced with an integrated fused infrared (IR) overlay; augmented reality (AR) capability; and wireless connectivity to enhance the "situation awareness, mobility, targeting, and lethality" of the US special operations forces.
Company officials at L3 Harris Technologies, the manufacturer of the GPNVG, confirmed that German distributor IEA Mil-Optics would be supplying‘hundreds’ of units to the German Armed Forces over an undisclosed timeframe.
The Fused-GPNVG, also known as the F-Pano, has also been designed with an Augmented Reality capability in addition to wireless connectivity to further extend the ‘situation awareness, mobility, targeting and lethality’ of special operations forces.
CMC proposes to develop an image overlay see-through display for a 4-tube night vision goggle system by integrating four of CMCs proprietary Holographic Imageguide Displays (HID) to provide a conformal full field of view (FOV) over a GPNVG.
Soon after CES, I got to see Creative MicroSystems Corporation (CMC) prototype that successfully couples laser beam scanning into a near to eye display waveguide. CMS is a quiet player in the AR industry that developed what they call Imageguide™ technology. They are receiving funding from the U.S. military and already delivered daylight viewable, 110° binocular display to an undisclosed U.S. government customer. According to their CEO, Bill Parker, they have overcome significant obstacles to use a laser approach and are continually improving its performance.
The CMC system was an early prototype, but it did demonstrate coupling laser beam scanning into a waveguide, which is not at all easy to do. For a waveguide to work, the light rays from the image being injected into the waveguide need to be moving parallel to each other, but with the LBS, each light ray is moving at a different angle as part of the scanning process as the mirror(s) tilt. With LCOS or DLP, the light rays illuminated their mirrors are highly collimated, and then the image has collimation optics.
