Abstract

The influence function of the actuators can be expressed as a Gaussian function. The exponent of the Gaussian function influences the reconstruction precision of the deformable mirror (DM). A finite element model of the PZT stacked array DM with 55 actuators was created, and each actuator was separately controlled. The influence of the structural parameters of the DM on the Gaussian index and coupling coefficient was investigated. Based on the simulation results, the design of the DM was optimized. In addition, using simulation, the fatigue life and working bandwidth of the new model were studied. Specific aberration surfaces were reconstructed. The results showed that the optimized DM had a smaller reconstruction error compared with the pre-optimized model. This study can be used as a reference for the design of DMs.
