But, you might still get ~33,000 counts/inch, I think.
Inductosyns are pretty simple in concept, a plate with two sections of serpentine PCB tracks, with them set up with a 90 degree shift between the two. And, a spar with a continuous serpentine running the whole length. Then, you have to drive several hundred mA through the spar. With a bit of an amplifier, you could get this to work with my (Pico Systems) resolver converter board. If the serpentine repeated every .1", then you'd get 40960 counts/inch. But, that might be too fine a pattern, requiring the two PC boards to be awfully close.
