Dr. Armitage is a consultant and engineering physicist, specializing in display technology and electro-optics. He has an extensive background in modeling display devices and systems. Recent publications include two SPIE articles on liquid crystal projection displays and silicon chip based imaging devices.

He began his specialization in projection devices and systems while working at IBM Research Laboratory in San Jose, CA and continued the work at Lockheed RDD in Palo Alto, CA. While at Lockheed he also focused on the related fields of spatial light modulators and optical signal processing.

Dr. Armitage has also done research in the fields of liquid crystals, semiconductors, and superconductors. He is credited as an inventor on eight patents and has published more than 40 articles and reports.

He was educated in England, receiving a BS degree in electrical engineering from Durham University, a MS in physics at University Newcastle-upon-Tyne, and a PhD in physics at Bath University.
