New video on detecting buried utilities

Associate Professor Vineet Kamat and Postdoctoral Fellow Suyang Dong are featured in a new video from MConneX on detecting buried utilities.| Short Read

Every sixty seconds in the United States an excavator hits a buried utility. Striking a cable, sewer, water, gas or fiber optic line can cause major damage as well as cut communities off from our crucial infrastructure. In addition, humans are often in the trenches to manually ensure that engineering standards are met.

In order to prevent future utility damage and ensure the safety of construction workers, the U-M Lab for Interactive Visualization has developed a new way to efficiently operate an excavator using their computer vision system, Smart Dig.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
