TECHNOLOGY FOCUS

LiDAR is a sensor that measures distance with light and can be used to detect obstacles for vehicles and robots or to scan buildings.

Over 100 companies are working to develop LiDAR solutions that can bring the required high performance and are more economic in terms of costs and much smaller for better integration in vehicles, robots, and drones so that they can be easily portable.

COURSE CONTENT

This course provides an overview of different LiDAR architectures in their use cases. Examples are Time of Flight (ToF) and FMCW techniques, where light can be scanned over the scene or illuminate the whole field of view with a flash.

The advantages and challenges of each case will be discussed in detail. The course will focus from System level to Transistor and Device level on all Electronic and Optoelectronic components and subsystems. Advanced discrete and integrated techniques and technologies like Analog/RF-Frontend topologies, Discriminator, ADC, ASIC process technology (CMOS, BiCMOS), (Co-) Packaging, different devices like Photodetectors and Laser Diodes as well as switches, switch drivers and power management techniques will be addressed extensively.

Solutions for miniaturization of novel LiDAR products through ASIC integration and (Co-) packaging will be shown with the goal how to reduce costs and improve performance.

WHO SHOULD ATTEND

This is a course about the development of LiDAR as a multi-disciplinary product, hence of interest for technical staff of different disciplines. They need to understand details and consider optimization on the higher product level and not only locally on a single discipline level. In general, it will be of interest to:

- Engineers, Physicists, Scientists, technical staff, and Students
- System Architects, Project Managers and Technical Managers
- Business Development Managers, Marketing Managers, who plan to be involved in specification and development of such a multi-disciplinary optoelectronic product and want to do business with it with fast Time to Market.
