​Capturing a Bullet in Flight

Published on: 23-Jun-2017

To prevent collisions, autonomous vehicles require precise, fast and lightweight photo sensors for safe navigation. Researchers led by Asst Prof Chen Shoushun from NTU’s School of Electrical and Electronic Engineering have developed a fundamentally new photo sensor technology that may be up to the task.

Called CeleX, the sensor does not produce pictures but features. Thanks to a special algorithm that looks only at relative change in light intensity and the speed of change, the sensor picks out moving objects and limits computation to these data points, omitting all unnecessary information from non- moving objects.
