Increasingly sophisticated ADAS needs to be able to detect objects at greater distances on the highway to ensure safety when cruising at higher speeds, meaning cameras for this purpose need lenses with a longer focal length. However, the optical quality of the windshield and the reduction in contrast can have a negative impact on the camera image quality. The LaVision Glass-SFR inspex system provides pointwise measurements of the spatial frequency response (SFR) of a windshield in the camera’s fieldof-view to characterize the optical quality of the lens/windshield combination.

The high-resolution camera-based system uses a large number of SFR targets to enable 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.
