In the context of Advanced Driving Assistance Systems (ADAS) technologies, the windshield is an intrinsic component of the optical system. Combined with the quality of the lens fitted to the camera, the optical quality of the windshield drives the performance of the system and guarantees automotive safety.

At Saint-Gobain Sekurit, we have implemented and validated the combination of wavefront error maps of our windshields and of camera lenses, measured separately, paving the way for an accurate calculation of the system MTF. We are able to assess the performance of any combination of a given windshield model and a given lens to select the best possible configurations.

We have also developed an analysis based on the decomposition of the wavefront error map on Zernike polynomials, allowing us to calculate a metric linked to optical aberrations to quantify the optical performance of the windshield.
