Autonomous Driving
A transportation revolution
Autonomous or semi-autonomous vehicles with Advanced Driver Assistance Systems (ADAS) use an array of sensors. Highest system reliability is a key criterion for safety-critical ADAS sensor technology. That's why, for most manufacturers, a Six Sigma approach with 3.4 failures in a million is inconceivable - a “zero-defect” strategy is often applied here, with less than one failure in a billion parts.
For LIDAR as well as RADAR sensors, for example, fogging must be avoided. To eliminate the possibility of moisture ingress, and thus fogging, these sensors must be gas-tight equaling a leak reject leak rate in the range of 10-6 to 10-7 mbar∙l/s in quality control during manufacturing. Helium vacuum leak testing with an instrument like the INFICON LDS3000 is the method of choice for many manufacturers.
