University Park, Texas (CBSDFW.COM) – In a story that sounds more 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, 3-D images of objects hidden around corners or obscured from view.
This technology, called synthetic wavelength holography, takes things like walls and turns them into light and imaging portals that can then be used to indirectly illuminate hidden objects.
In a study published in Nature Communications, the scientists said the new technology could be used to take pictures through fog or develop systems that allow drivers to detect what’s going on with them.
Part of the technology was developed in SMU’s Photonic Engineering Laboratory, led by Prasana Rangarajan, associate professor at SMU’s Lyell School of Engineering, and second author on the study.
“By combining laser light from two closely spaced colours, we synthesize an optical tone that is reflected off obscured objects,” said Rangarajan. “Observing the relative change in the phase of the transmitted and received visual tone allows us to identify hidden objects (echolocation) and assemble a three-dimensional image of hidden objects.”
