About Matthias

Born in the early seventies in Northern Germany I graduated in Physics at the University of Ulm. I worked for the BOSCH automotive group in Stuttgart before joining DALSA in 2000. Since then I have worked on layout, design, project lead, architecture and program management for various DALSA CMOS image sensors. I enjoy creating sensors and seeing them through production and implementation at the customer end.

Spectral Cognisance 4 – Is Lux more than Luxury?

Feb 15, 2013

Coming from a Machine Vision World, “Lux” and Human Vision have been a mystery to me for a long time. Thankfully, we have had some customers in the application of human vision and I’ve been able to remedy this situation. … Continue reading

The Angle on Optical Acceptance

May 2, 2012

In my last post – not the April Fools post – but the one before…  I described how pixel Fill Factor plays a role in the optical efficiency of an image sensor. The Optical Acceptance Angle is directly related to Fill … Continue reading
