Paper Abstract

Although analyses general enough to account for both the temporal and spatial characteristics of the adaptive optical system exist, they are complex and require detailed information regarding the wave front sensor, the deformable mirror, and the control algorithm. This investigation develops a frequency domain analysis that predicts the performance of an adaptive optical system having an arbitrary temporal response. The analysis takes into account aperture piston and tilt removal and spatial bandwidth limitations due to the wave front sensor's finite subaperture size and the deformable mirror's finite actuator spacing. The unique aspect of this model is the relative ease with which performance characteristics of different spatial and temporal system response functions can be investigated.
