Evaluation of bimorph deformable mirror performance through Zernike polynomials reconstruction

Wavefront correction efficiency by bimorph deformable mirror could be estimated through the modal functions’ reconstruction. Zernike polynomials at this point could be considered as an effective and easy-to-use tool for this purpose. The 37-channel bimorph deformable mirror was able to reproduce wavefront aberrations up to 7th order with reasonable amplitude and residual RMS of less than 0.05 μ.
