Abstract :
The paper describes two similar deformable mirrors that will demonstrate the feasibility of nanolaminate-based deformable mirrors over a wide range of size scales. Two complementary technologies: high-spatial-density electrostatic actuators and thin, flexible, lightweight nanolaminate foils are combined. Electrostatic actuation of MEMS-like structures provides densely-spaced, repeatable deflections on the order of 10 mum. Nanolaminate foils provide a mirror surface that is simultaneously flexible enough to deform under electrostatic forces and tough enough to survive handling and bonding
