To become a standard feature in all car classes, lidar sensors need to be semiconductor-based, thus more compact, cost-effective and robust
Highly automated driver assistance systems, heading towards fully autonomous, require multiple sensor systems. Together with camera and radar, lidar is a key technology to sense the environment around a car. Infineon provides highly flexible solutions with best in class product performance, which were created by design to complement each other. Using the latest developments in technology within a small form factor, cost-effective solid state lidar sensors for mass-market adoption can be developed to enable very accurate object tracking and recognition. Lidar-light detection and ranging measures moving targets and static objects based on the principle of time-of-flight; the distance to an object is measured by calculating the time taken by a pulse of invisible light to travel to an object and back to the sensor.

Solid state lidar concept from Infineon
The concept for Lidar is based on a 1D MEMS mirror scanning architecture: laser pulses are stretched into a vertical line and scanned horizontally by the MEMS mirror over the field-of-view. A static detector captures the reflected light from objects.
What Infineon offers
Infineon will manufacture and supply several automotive qualified components for a lidar sensor to support SOP 2020+: MEMS mirror, ASIC to drive and control the MEMS mirror, receiver module, AURIX microcontroller as well as power supply/management components.
