Advanced Driver Assistance Systems (ADAS) for high autonomous driving levels need to detect objects at longer distances, far in front of the vehicle, to ensure a safe car control during highway cruising at higher speeds. Cameras for this purpose need lenses with a longer focal length. The image quality of these cameras suffers from the optical quality of the windshield in front of them, which can cause a quality decrease due to contrast reduction.

The LaVision Glass-SFR inspex system provides pointwise measurements of the Spatial Frequency Response (SFR) of windshields in the area of the ADAS camera to characterize the optical quality of the lens – windshield combination. The high-resolution camera-based system uses a large number of SFR targets to allow the analysis of different viewing angles through the windshield simultaneously. The system additionally provides optional 2D evaluation of the windshield’s optical power at the ADAS area with high spatial resolution in the sub-millimeter range.

The flexible usage of customer ADAS lenses with LaVision´s Glass-SFR inspex system offers the analysis of different lens and windshield combinations at an early stage and helps drastically reduce development time.
