ADAS for autonomous driving needs to detect objects at greater distances, far in front of the vehicle, to ensure safe control at highway cruising speeds. Cameras for this purpose need lenses with a longer focal length. The image quality of these devices depends on the optical quality of the windshield.

The LaVision Glass-SFR Inspex system, which will be on display at the expo, 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 simultaneous analysis of different viewing angles through the windshield. The system also provides optional 2D evaluation of the windshield’s optical power at the ADAS area with high spatial resolution in the submillimeter range.

The flexible use of customer ADAS lenses with LaVision’s Glass-SFR Inspex system enables the analysis of different lens and windshield combinations at an early stage and helps to drastically reduce development time.
