I’m trying to build an all analog driver system to drive X-Y scanners for use with some old gas lasers.
Back in the mid-1980s, a group of us junior college geeks enjoyed harvesting HeNes and 60X Argons from Surplus Sam of Southern California. Some of us pointed these lasers through galvos for a then, state of the art, spiro projection setup.
I used to have a system my friend Jeff designed, and I built, using Burr-Brown 4423 Quadrature Oscillators. The 4423 is a neat, but dated chip, which outputs both analog sine and cosine – ideal for an X-Y mirror setup. No DACs needed. It made some beautiful images.
I think my ex-wife got rid of the console system along with a bunch of defunct PCs, because it was built inside a PC chassis.
My searches on the net for "analog driver scanner laser schematics" are not producing the results I want. Many of the hits are for digital to analog systems. I recognize, in this day and age, digital is the way to go. But I’d like to build a complete analog system, again, using the above mentioned Burr-Brown oscillators.
Can anyone point me in the right direction for locating an existing design?
Are there any analog veterans left in this industry?
