Abstract
In this paper, the fabrication, modeling and characterization of an all optically addressed spring patterned silicon-nitride deformable mirror Micro-Electro-Mechanical-System (MEMS) device is reported. This device is biased through combinations of high frequency AC and DC voltages. The experimentally verified theoretical modeling for this device shows mirror deflection saturation as a function of light intensity appropriate for dynamic range compression deconvolution. It was experimentally verified that the spring MEMS deformable mirror device has response up to 10 MHz, which opens the possibility of correcting supersonic turbulence as well as atmospheric turbulence.
