RSM34: Feedback Control and Electronics for Deformable Mirrors

The goal of this project is to design control electronics for the deformable mirrors demonstrated by Michael Helmbrecht. The first part of the circuit design to be performed is control of a single mirror past its pull-in instability. This will extend the possible travel range for a given drive voltage, which is very important, as deformable mirrors benefit from extremely large travel range. The second circuit design goal is to design addressing circuitry to enable mirror scaling from a few actuators to the hundreds or thousands necessary for extreme adaptive optics.
