About Eric F

Eric has been involved in the world of photonics for more than 25 years. Most of that time has been spent developing image sensors, first with CCD technology, and for the past 14 years with CMOS. Favourite activities outside of work are family and almost anything related to music.

256 Shades of Grey in the World of Machine Vision – Part 2

Nov 13, 2012

In my last post I described the role of shot noise in determining the ability of machine vision systems to detect objects. Specifically, I pointed out that in my experience, shot noise rather than detector read noise is more often … Continue reading

256 Shades of Grey: The Story of Shot Noise, Part 1

Sep 18, 2012

People use the term image noise somewhat loosely to capture any non-ideality that detracts from the “ideal” image. Contributors to noise include fixed pattern noise (FPN), photoresponse nonuniformity (PRNU), temporal random read noise, and even artefacts like electronic exposure control … Continue reading

All That is Old is New Again

Jun 5, 2012

Most would point to the middle part of the last century as the birth of electronic imaging. RCA, Philips, EMI and others introduced several generations of tube image sensors with names like Orthocon, Plumbicon, and Vidicon. In all cases the … Continue reading

The Art of Making Large Image Sensors (or Quilting with Silicon)

Feb 7, 2012

While most of the semiconductor world is busy shrinking chips to ever smaller sizes, high performance image sensor manufacturers are often pushing the bounds of chip size in order to achieve ever higher image resolution. In the 1980s and early … Continue reading
