3D Holographic Technology
Our technology is not only impressive. It’s proven. Zebra is at the forefront of holographic visualization technology. Zebra Imaging's patented holographic 3-D imagery represents a leap forward in the art and science of 3D three-dimensional imaging. Based on over fifteen years of research beginning at the MIT Media Lab and over 30 patents, the company offers some of the most innovative holographic products and technology in the world.
The Process
1. Raw 3-D graphic data of almost any kind- including: LIDAR, Aerial photographs, CAD, CAM, can be used to make a hologram.
2. The model data is processed and rendered by our proprietary rendering engine. Each digital hologram is composed of thousands of hogels (like a three dimensional pixel). The model data is broken down into subsets for each hogel.
3. A hologram of a 3-D model is formed by recording the interference pattern of two laser beams. One laser beam is encoded with the datausing an LCD screen which then scatters the image onto the recording medium. The second beam serves as a reference beam. The two beams are brought together and interfere on the recording medium (a photo polymer film). Each point in the object acts as a point source of light, and each of these point sources interferes with the reference beam, giving rise to an interference pattern. The interference pattern of light and dark areas, similar to zebra stripes, is recorded in the photo polymer. This process is repeated for each hogel to build the entire hologram.
4. After recording and processing the film, the hologram is illuminated by a light in a similar position to the reference beam it was recorded with. Each hogel’s recorded interference pattern will diffract part of the reference beam to re-construct the data beam. These individual reconstructed data beams add together to reconstruct the whole 3-D model. The viewer perceives a 3-D image reconstructed in reflected light which is identical to the 3-D model data.
Emerging Technology
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.
