Sensors in self-driving cars must resolve multiple performance challenges that involve temperature, illumination, reflectivity, navigation — and even cybersecurity.
HANK HOGAN, CONTRIBUTING EDITOR
Self-driving cars bring both opportunities and challenges to photonics-based sensors. Autonomous vehicles will need dozens of sensors ofmany types — lidar, camera, radar, and
ultrasonic — and many sensors on millions of vehicles make the potential opportunity significant.
The challenges are many as well. Cameras and lidars must operate for years across widely varying temperatures, illumination levels, and target reflectivities, while reliably producing the data needed for safe
