Interferometric calibration of a deformable mirror


This tutorial discusses the static calibration of a deformable mirror using a Twyman--Green interferometer setup, combined with single-frame fringe analysis for phase extraction. We provide a reference implementation for this method in the form of a toolbox written in Python.  In addition, we include detailed instructions to build a compact, slot-in interferometer.  This protocol, accompanying software, and hardware design facilitate calibration of deformable mirrors for a range of applications.
