TechnologyZebra Imaging's proven, patented and award-winning holographic visualization technology represents a significant leap forward in the art and science of 3D imaging. Based on more than fifteen years of research that began at the MIT Media Lab and led to more than 30 patents and counting, Zebra Imaging offers some of the most innovative holographic products and technologies in the world.

We use a simple approach to this complex technological discipline, prioritizing interactive engagement and ease of use. We aim to provide our valued clients and partners with advanced visual tools that facilitate communication and support higher levels of design, development and achievement. Digital holography ultimately provides real-world uses for 3D data, establishing the science as the future of 3D for many different research, construction and consumer projects.

Our Process
3D data is the foundational component of a hologram. Raw 3D graphic information can come from many sources, including computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAM), medical imaging technologies, LIDAR, aerial photography, and radar and laser scans.

Our proprietary rendering engine processes the 3D model data by breaking it down into subsets for each hogel (a three dimensional pixel). Each digital hologram is composed of thousands of hogels.

The hologram of the 3D model is created by recording interference patterns of two laser beams. The first laser beam, encoded with the 3D data, scatters the image onto the recording medium using an LCD screen. The second laser beam provides reference for the first. The two beams converge and interfere on the recording medium (a photo polymer film). Each point in the objects acts as a point source of light and each of these point sources interferes with the reference beam. This creates the interference pattern.

The interference pattern is composed of light and dark areas and looks similar to zebra stripes. It is recorded in the photo polymer film. This completes the process for just one hogel, so it is repeated for each subsequent hogel until the hologram is complete.

After the hologram records and processes the film, it can be viewed by a person without the need for special visual aids by using a light that mimics the original reference beam used in recording. This light's reference beam is diffracted by each hogel's specific interference pattern, and the individual patterns are reconstructed to portray the original 3D model. The 3D image that the viewer perceives is really the 3D model data reconstructed in reflected light.

We’ve spent years working with high-profile customers at the federal government, and our agile team of holographic experts has collected over 30 patents, with many more pending in the U.S. and abroad. We offer an approach that is trustworthy and reliable, and we continue to push boundaries by creating compelling 3D visual experiences in fields such as defense and intelligence, architecture, engineering, construction surveying, geospatial, homeland security and more.
