Holographic Waveguide Visor Display (HWVD)

ABSTRACT: The objective of this Phase II proposal is to develop and prototype a binocular, see-through, monochrome holographic waveguide helmet mounted display (HWVD). The optical system will couple a commercial high resolution 1920x1080 pixel LCOS microdisplay with a state of the art holographic waveguide. Utilization of the waveguide will allow for a wide 40 degree field of view (FOV), while having a large 30x30 mm eyebox. The prototype will be mounted in an existing Air Force helmet. With the advantages obtained by use of the holographic waveguide and the small LCOS microdisplay, the proposed HWVD system will enable significant cost, volume, and weight reductions as compared to existing CRT type designs. The design will also address power and efficiency requirements consistent with a pilot HMD system. Use of an LED light source will allow for utilization of specific wavelengths tailored to specific applications, and allow for high brightness requirements. Using the holographic waveguide development plan, the the path towards a full color,high resolution HWVD with a panoramic 120 x 80 degree FOV will be demonstrated. A second visor with a curved waveguide will be developed. BENEFIT: A modular concept is proposed for a binocular helmet mounted display system with holographic waveguide and high-resolution LCOS technology. These technologies will be combined with a unique optics design for achieving high levels of brightness and contrast ratio. This will dramatically improve the HMD quality for both military and commercial aircraft. The modularity of the mechanical concept will enable the support of multiple platforms and application with only one basic design. Accumulated knowledge during this effort will enable us to adjust rapidly to a variety of unique military and commercial display applications and expand the market.
