Hi, I'm Dick Lyon. I am a research engineer in Silicon Valley, California.
Some of my work prior to Wikipedia is linked on my new tech home page dicklyon.com.

[edit] History bug
I've been bitten by the history bug, so I've researched the history of several topics, and added history sections, comments, or links, to articles, such as these:
- Actinograph
- Aperture
- Bulb (photography)
- Circle of confusion
- Diaphragm (optics)
- Diffraction
- F-number
- Hyperfocal distance
- Nyquist–Shannon sampling theorem
- Pixel
- Scanline rendering
- Zeiss formula
[edit] Movie-star friend
- My friend Wally Rippel, long-time electric car maker and winner of the first transcontinental electric car race of 1968, is one of the stars of this new (June 2006) documentary. I got to see a free screening of it, hosted by my friend Alec who provided some of the footage for the movie. I recommend it highly for the range of inside viewpoints that it provides on energy and transportation issues.
[edit] Contributions to the Wikipedia
My contributions are mostly related to photography, photometry, and signal processing so far. My contributions on these articles range from very small to total rewrite; see the respective article histories.
