Abstract

For the past several years Itek has been involved with the development of deformable mirrors for active optical systems. Several innovative techniques have been developed to deal with the problems of device-design and resonance damping. Designing a device for a required amount of wavefront correction has been approached by utilizing a computer program, which calculates actuator voltages and error fit values based upon actuator response functions, arrays, etc. Resonant modes present in high bandwidth deformable surface devices have been dampened by energy absorption techniques. Resonance amplitudes have been attenuated by as much as 1/60.
