Paper Abstract

A calibration procedure is described for improved modeling of a continuous facesheet deformable mirror. A resistive force of each actuator as it attempts to move to its commanded position is modeled as a linear spring force. A force associated with the resistance of the facesheet to bending is modeled as a moment that exerts a force on the actuators. The resultant first order finite element model is parameterized by a gain on each actuator channel and a ratio relating the average actuator spring constant and the facesheet bending moment coefficient. Example experimental results are presented indicating that modeling accuracy is improved by use of the first order finite element model.
