LIDAR for ADAS and Autonomous Sensing

.Advanced Driver Assist System (ADAS) and autonomous vehicle technologies have disrupted the traditional automotive industry with potential to increase safety and optimize the cost of car ownership. Light detection and ranging (LIDAR) sensing, a sensing method that detects objects and maps their distances, is seeing rapid growth and adoption in the industry. However, the sensor requirements and system architecture options continue to evolve. This course will provide the foundation on which to build LIDAR technologies in automotive applications.

The seminar will begin with a review of infrared basics: electromagnetic spectrum, spectral irradiance, night vision and eye safety. The instructor will dive into LIDAR – flash, scanning, wavelengths, lasers, detectors, scanners, range and resolution calculations, optics, thermal design, challenges to automotive qualification, and sensor fusion. The course will conclude with a short discussion on trends and challenges facing optical sensing in autonomous vehicles.
