There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Lidar vehiclesSPIE, the International Society for Optics and Photonics, has released a news story that features Georgia Tech lidar (light detection and ranging) research as it relates to autonomous vehicles.
The project, joint between the School of Electrical and Computer Engineering (ECE) and the Georgia Tech Research Institute, has shown how interference can occur between vehicles that each have their own lidar sensing systems. These lidar units are designed to sense their surroundings and thus keep track of the locations of all surrounding vehicles. However, this work has shown how false returns can occur when there are multiple vehicles, each with its own lidar systems.
Any vehicle, in addition to receiving its own lidar returns, may unintentionally receive returns from other vehicles’ lidars, thus indicating they are farther away or closer than they actually are. This erroneous range information could lead to disastrous consequences.
This research is being conducted by ECE Ph.D. student Gerald Ben Popko, currently at the U.S. Military Academy at West Point, ECE Regents’ Professor Tom Gaylord, and GTRI Senior Research Engineer Chris Valenta. According to Gaylord, “Autonomous and self-driving vehicles are the wave of the future. This research shows that appropriate precautions will be necessary to ensure the safety of all drivers.”
