I remember the old 3-pass flatbed scanner we had at university. Had three separate lamps. It was fun watching the thing do its work. > You _can_ design a monitor like that.

[etc] There's another kind of screen I read about a few years back. It was based on a dirt-cheap black & white CRT display, with a fancy three-layer LCD-based filter in front of it. The screen would first activate the "red" filter and draw the "red" pixels, then cycle through "green" and "blue". Of course, it had to run at three times the scan rate of a colour CRT just to keep up. It was used in an oscilloscope but I'm not sure who made it. May have been Tektronix. I presume it was just too expensive to scale, in addition to the problems imposed by raising the refresh rate. > PS: One thing I've been wishing for for a long time is a > dual-trace/dual-colour beam-penetration oscilliscope.

Digital scopes with raster displays have been around for ages. Even with a colour screen if your pocket is deep enough. HP have even released a scope with voice recognition and an inbuilt hard drive. Personally I love the Tektronix colour DPO screens. What I want in a scope is channels which are isolated from each other, and independent timebases for each channel. > But I'm a "programmer with a soldering iron", so this really > isn't my field.) I'm the exact opposite. I'm an electrical engineer who dabbles in programming. And my code "hoovers", mainly because I don't define my specfications before I start dabbling on a project... much like breadboarding a circuit :) Cheers, - Dave http://www.digistar.com/~dmann/ (out of date) - This message is from the Pentax-Discuss Mail List.
