SMU Researchers Help Develop Technology That Allows Cameras To See Around The Corner – CBS Dallas / Fort Worth

UNIVERSITY PARK, Texas (CBSDFW.COM) – In a story that sounds more like science fiction than science fact, researchers at Southern Methodist University and Northwest University have developed a new technology that allows cameras to capture high-resolution images and holograms of objects, whether or not hidden behind corners are visible.

The technology known as synthetic wavelength holography takes objects like walls and turns them into lighting and image portals that can then be used to indirectly illuminate hidden objects.

In a study published in the journal Nature Communications, scientists said the new technology could be used to capture images through fog or develop systems that allow drivers to see what’s coming around the corner.

Part of the technology was developed in SMU’s Photonics Architecture Lab under the direction of Prasanna Rangarajan, Assistant Professor at the Lyle School of Engineering at SMU and co-author of the study.

“By combining laser light from two closely spaced colors, we synthesize an optical beat note that is reflected by hidden objects,” said Rangarajan. “Monitoring the relative phase change of the transmitted and received optical beat note enables us to localize hidden objects (echolocation) and to compile a hologram of the hidden objects.”
