Curvature Sensing and Compensation for Adaptive Optics:
A Computer Simulation
Abstract
A principal cause of bad transmission of electromagnetic waves is the
distortion due to atmospheric disturbances. The received wavefront phase has
been affected. Therefore, a way to improve transmissions, or imaging in the
optical case, is to restore the original phase of the wavefront to remove the
distortions. The adaptive optics concept consists of making a real time
estimate of the wavefront phase have a deformable active mirror match this
estimate, whereby the wavefront will automatically be corrected when light
reflects on that mirror.
