Paper Abstract

A novel vibrating membrane mirror (VMM) based on the mechanical concepts of vibrating membranes is proposed. This mirror has the capability of being a proper alternative for the traditional optical mirrors. A finite element model of membrane mirror is developed using ANSYS Workbench and its dynamic characteristics extracted to compare with main wavefront aberrations. The similarities between normal modes of a vibrating membrane and Zernike polynomials, which approximate mathematically distorted wavefront, are investigated and the degree of similarities is calculated using RMSE criteria and effective radius. To eliminate unwelcome vibrations of actuators, the excitation ring has been introduced.
