Abstract
For high-resolution retinal camera, we have developed an adaptive optical system with a silicon-membrane deformable mirror (DM), which is electrostatically actuated by 85 electrodes. The square voltages applied to the electrodes are mathematically calculated by a linear combination of base templates, each of that approximately forms a specific Zernike-modal shape. We present a derivation method how to obtain new templates. The suitable coefficients for the template combination are derived by the least-squares method. By using the method, we have successfully improved the wavefront compensation performance in the adaptive optics with the DM.
