Connected, Autonomous, Shared and Electric (CASE) mobility solutions need sensors. Lots of them. The rapidly changing landscape of advanced driver assistance systems (ADAS) as it mutates towards autonomous is putting LiDAR (Light Detection and Ranging) technology firmly in the spotlight. LiDAR is said to be the most important of the sensor suite that enables the different levels of driver autonomy. Continuing just-auto/AIC's series of research snapshots, Matthew Beecham examines the whys and wherefores.
