MrFit: mirror simulation software

MrFit is a program for simulation of membrane and continuous facesheet deformable mirrors ("Mr" means mirror and "Fit" means to fit a specified wavefront). It calculates the voltages to be applied to the actuators to achieve the best possible compensation for a specified wavefront aberration, defined as a combination of Zernike terms.


The program shows the surfaces of the wavefront, the best fit with a specified DM, and the approximation error. The output can be obtained as a grayscale plot, interferogram, or a 3D surface.  The software  can take into account the effects caused by the clipping of the actuator voltages, providing realistic output accounting for the limited stroke of the DM actuators. For more information, please refer to the program manual.

The full commercial version of the program will simulate  any circular membrane or a continuous facesheet DM, with any number and geometry of actuators.

 A free version of the software can be downloaded here.  It simulates only the deformable mirrors produced by OKO Technologies. To minimize the download size, some of the mirrors are not included in this version. You can download separately configuration files for 19-ch 30mm PDM19-ch 30mm PDM optimized for correction of the low-order aberrations37-ch 50-mm PDM, and 79-ch 50-mm PDM.

Please contact OKO Technologies for any further information about the commercial and the free version of the software.
