Researchers Improve ToF Resolution 1000-Fold Using Computational Approach
CAMBRIDGE, Mass., Dec. 28, 2017 — In a novel approach to time-of-flight (ToF) imaging, researchers correlated the principle of heterodyning to increase ToF depth resolution 1,000-fold. Higher ToF resolution could enable accurate distance measurements through fog, removing a major obstacle to the development of self-driving cars. At a range of two meters, existing ToF systems have a depth resolution of about a centimeter. In contrast, a new ToF system developed by an MIT team has a depth resolution of three micrometers at
