Analysis on fitting capability to human aberrations of bimorph deformable mirrors

This study adapted simulations to analyze the fitting capabilities to human aberration of three kinds of Bimorph Deformable Mirrors (DMs) with different spatial resolutions, especially the capability to fit to 3~ 35th orders of Zernike static aberrations and the human aberrations, including the eye of diseases. It's shown that Bimorph DM is well suitable for fitting to low-order aberrations with the error less than 0.15. As the spatial resolution increased, the capability of fitting aberrations enhanced totally. Compared with traditional discrete piezoelectric DM, 35-element Bimorph DM had smaller fitting error on the first 20th Zernike aberration. This simulated analysis provided an analytical method for the selection of Bimorph DMs for high-resolution human eye imaging systems. In addition, it provided a research foundation of further improvement of the Bimorph DM in fitting aberrations capability.
