zach asks: why not put it on the external shaft? georgi replies not straightforward to use that as the position of the grating. zach/Alex say it could be calibrated

cpo says: interpolate? georgi says the turnaround point would break interpolation.  turnaround time cpo says: mechanical motor turnaround time either fast or slow could work with a 10kHz.on timescale of 10kHz sampling should work.  in particular, turnaround time feels likely much slower than 10kHz sampling period?

alex w.: could add time-staggered 10kHz encoders to artificially increase rate

georgi says: need to understand the upper limits. interpolation may be too short-sighted. fast encoder is best.

Matt says we may have an existing board that could do the readout/timestamping
