Adaptive optics aberrometer and wavefront corrector using a twisted-nematic liquid-crystal on silicon chip
Through the application of adaptive correction, both the permanent and changing aberrations of the eye that affect vision acuity are compensated for in order to provide diffraction-limited imaging. This thesis investigates the aspects of establishing an adaptive optics system for the correction of …

Adaptive Pattern Modeling for Large Reflector Antennas
… the focal ratio and feed pattern. In subsequent adaptive methods, parameters of this model are calculated using measurements of interference signals. The corrected pattern model improves the prediction of the change in the true pattern for future times. The methods are compared by (1) comparing …
