Abstract

Flexible mirrors widely used for wave front correction, can be deformed to any desired complex shape through the application of control voltages. Finite element method has been used for computing the value and location of voltages. The thickness of the mirror being very small, it behaves nonlinearly. The paper presents the method of computation of influence matrix to relate deformed shape with the pressure to be applied to obtain the deformed shape.
