Systems and methods include determining whether a parameter of a hogel beam, from a set of hogel beams, is within one or more thresholds. The one or more thresholds are based at least in part on one or more parameters of a first set of hogel beams. In response to the parameter being outside of the one or more thresholds, new values are determined for the parameter based at least in part on one or more parameters from a second set of hogel beams.

ABSTRACT: Zebra Imagings proposed approach for the HVD Phase II will advance the state-of-the-art Urban Photonic Sandtable Display Program (UPSD) light-field display architecture and incorporate the successful results of the AF131-023 HVD Phase I research. The proof-of-concept HVD Phase II optical stack will consist of a 4K SLM under a planar array of hogel optics. A design for a 90 hogel optical system will be developed comprising of a tightly arranged 2D array of hogels. The drive electronics will be integrated into the optical stack and be located in close proximity to the SLM. The integrated optical stack will represent the base field replaceable unit (FRU). Optical stacks may be tiled together to create large displays with board-to-board interconnects providing data relay. The HVD Phase II effort will use off-the-shelf (OTS) GPUs for hogel radiance image computation which will be connected to the driver board over USB or cabled PCIe. The final program deliverable will be a multi-modulator proof-of-concept light-field display with an active area of ~752mm. The light-field display will project a perspective correct, full-parallax, 3D light-field for all views within the projection frustum and can be used for a variety of collaboration, training or simulation applications.; BENEFIT: Like most disruptive technologies, the interactive LFD will bring science fiction 3D visualization into reality. In the future, light-field displays will be in the center of every war room, command center, medical facility, research institute, and entertainment complex; and will provide the ability to collaborate with multidiscipline decision makers and stakeholders, increase their level of understanding and comprehension of complex problems, and allow them to make well informed decisions quicker and with greater confidence. Target Markets The 3D imaging and visualization market is forecasted to be a ~$10 billion dollar industry by 2018 with Defense/Security and Healthcare/Medical representing ~63% of the worldwide market. Industrial, Architecture/ Engineering, Geospatial visualization and Media and Entertainment round out the rest of the market. While the light-field display developed in this effort will be application agnostic and can be used for a variety of purposes, the initial markets will be for battlespace and medical visualization within government and commercial organizations. Since battlefield visualization and sports visualization have similar requirements, visualization of sporting events (such as boxing/basketball) will be the first entertainment market addressed. Medical The largest commercial market is within medical education, surgical simulation, and medical training. Zebra Imaging is currently establishing 3-4 working groups of medical experts to independently evaluate and determine market potential for a number of medical applications. The working groups will determine 3-4 market application and derive requirements for each. The resulting data will help prioritize and guide the LFD development. DoD Applications Applications with the DoD range from medical simulation and training to battlefield visualization. Zebra Imaging has established relationships with a number of large government contractors including Boeing, Lockheed Martin, Raytheon, and Electric Boat that have been instrumental in providing feedback and support in the development of light-field displays. These companies will continue to advise on the future needs of the military from an integration perspective.

ABSTRACT: Zebra Imaging"s proposed Holographic Video Display solution will be based on proven research, technology and prototypes to meet the HVD objectives and will allow for the natural viewing of streaming 3D data from a variety of sources without the need for glasses, head tracking or any other supporting devices. Zebra Imaging's light-field technology is based on the concept of a 2D array of light-emitting holographic elements ("hogels"), which reconstruct a full-parallax light-field above and below the emission surface of the display, allowing the viewer a perspective correct visualization within the display view volume. Interaction within the visualization volume can occur with a number of off-the-shelf (OTS) devices including gesture input devices, 3D wand pointers, depth cameras, ball mice and touch panels. Overall, the display architecture and systems will be designed in a modular fashion allowing for a sustainable roadmap of evolving capability and performance. BENEFIT: Aligned with the HVD solicitation Phase III"Dual Use Application"goal, Zebra Imaging's primary commercialization strategy is to design and build a display that is data and application agnostic and that can be used for a variety of purpose. Such is the case with a 2D monitor which can be connected to any computer or gaming console through a standard interface, Zebra Imaging's objective is to define the interface for 3D holographic displays and build the first commercially viable light-field display to that standard. A particularly good example of this multi-use strategy exists with a collaborative display that can be used for commercial sports and events visualization as well as battlefield training, monitoring, and planning visualization for the DoD. The two use cases require wide angles of view for seated and standing viewers, 30hz update for live action viewing, natural and unencumbered interactivity and portabilityfor placement in a variety of locations from public venues to forward operating bases.

The objective of the proposed effort is to demonstrate the feasibility of the scalable 3D display technology by Zebra Imaging to produce realistic auto-viewable 3D images for Air Force mission applications related to air, space and cyberspace. A display producing such holographic images provides intuitive visualization of three-dimensional (3D) data and scene information from a wide range of data sources. Zebra’s technology provides rapid, interactive viewing of all types of 3D data, converting 3D scene data into a spatial image that occupies a 3D image volume, much like the holographic images produced by traditional hardcopy optical holograms. Animations and interactive content are displayed as bright true-3D images, viewed automatically, with no special viewing apparatus or glasses, with full parallax for proper 3D perspective from every viewer position. The core technology combines custom (and off-the-shelf) components to control the amount and direction of emitted light-field. As will be shown in the Phase 1 effort, it provides accurate, unencumbered, scalable and updatable presentation of critical data for multiple users. It will provide the scalable, auto-viewable display to depict multi sensor and other information and associated data, allowing real-time multi-user interactivity. BENEFIT: By producing spatial images with holographic realism, Zebra 3D displays are a valuable visualization tool. The display can be integrated with existing applications to facilitate communication of intelligence for team-based training, battle space management, mission planning and rehearsal, and interpretation of real-time data. This technology is suitable for a wide spectrum of Department of Defense (DoD) applications, ideally those that include graphically-intense applications. The 3D display will accurately and intuitively present complex real-world data to facilitate rapid discernment and clear communication of intelligence to support planning, decision making and mission execution. It will satisfy an immediate and growing need in a broad swath of sectors in the military, for operation mission planning and reconnaissance. As the number and sophistication level of sensors in the military theater increase, potentially critical data can lose utility without a means for rapid discernment and contextualization. Most of this data is co-located, visual, and occupies a three-dimensional volume in the modern battlespace. Current display technologies that claim to provide “3D images” fall short when visualizing this kind of data: they lack depth cues and therefore accuracy; many are not practical for multiple users; most are not scalable.
