Nice! I can't believe I didn't see this earlier!

Too few sensors and too big assembly to resolve it.
A Linear Sensor Arrays ICs combined with lens like the TSL202R (Digikey) or the ILX526A (Aliexpress) may be used .
A simpler and cheaper aproach will be using an optical mouse sensor.

Will this detect precision movement down to .01 inch?
