Deformable mirror optimization

DM is optimized via stochastic parallel gradient descent (SPGD) algorithm using a PSF quality metric in both views simultaneously. The following example shows how fluorescent bead images (PSFs) in the two views change over iterations.

Full source code is available at dm_optimization. The total run time of such optimization is 2-3 minutes, limited by the camera frame rate and speed of computations.
