Overview of LIDAR and Infrared Cameras for ADAS and Autonomous Sensing

This ½ day technical session is an abbreviated version of the 2 day SAE course on the same topic. The session will begin with a review of Infrared basics - electromagnetic spectrum, spectral irradiance, night vision and eye safety. We will then dive into LIDAR – flash, scanning, wavelengths, lasers, detectors, scanners, range and resolution calculations, optics, thermal design, challenges to automotive qualification and sensor fusion. The second half will cover Infrared camera topics with focus on driver monitoring for interior and machine vision for exterior. We will review rolling and global shutter imagers, wavelength selection, use of secondary optics, continuous vs pulsed IRED operation, thermal design, power consumption, eye safety certification and HMI considerations. A brief review of iris recognition, cabin monitoring and face recognition. We will end with a short discussion on trends and challenges facing optical sensing in autonomous vehicles.
