Automotive LiDAR deicing: ensuring a clear field of view for sensors in autonomous vehicles

Automotive LiDAR is the driving technology for autonomous and semi-autonomous mobility. However, reliability of LiDAR through harsh weather is a key challenge on the road to fully autonomous driving. Ice, snow or fog on LiDAR cover lens obstructs the sensor’s field of view, impeding accurate detection of objects on the roadway. Canatu LiDAR heaters are needed to keep the cover lens clear of weathering disturbances, enabling precise 3D LiDAR mapping in all weather conditions.

Canatu’s CSO Samuli Kohonen presented the automotive LiDAR heaters at the 4th LiDAR Tech Forum from November 16-18, 2022 in Suzhou, China. Watch recorded presentation below to discover why reliability in harsh weather risks mass adoption of automotive LiDAR, and how Canatu film heaters can support autonomous driving in any weather.

The Canatu LiDAR heaters offer high transmittance at near infrared light combined with effective heating. Canatu film heaters are entirely wire-free at LiDAR field of view ensuring even, fast and power-efficient deicing across the whole surface without optical distortion or laser beam deflection. Heaters can be thermoformed or high-pressure formed into any 3D shape, and film insert molded into the automotive LiDAR cover lens.

The final molded part is LiDAR permeable and wire-free, providing a clear field of view for the sensor to create and accurate 3D LiDAR mapping. The performance can be further enhanced by applying functional coatings, such as anti-reflective or hard coating on the back and front surfaces. Our heaters can be flexibly tailored to meet optical, heating and design requirements across a range of input voltages.
