Title: The Innovations of Donald W. Davies
Introduction
Donald W. Davies is a notable inventor based in Torrance, California. He has made significant contributions to the field of adaptive optics, holding a total of 7 patents. His work focuses on improving optical systems, particularly in correcting wavefront aberrations.
Latest Patents
Among his latest patents is the "Low signal-to-noise ratio branch-point-capable adaptive optics sensor." This invention features a lateral shearing interferometer wavefront sensor system that employs a double-shear/full aperture approach to correct for branch points in the wavefront of an optical beam that has been aberrated. The system includes a beam splitter that divides the beam into two split beams, a beam shifter that adjusts the position of one beam relative to the other, and a beam combiner that merges the two beams to create an interference pattern. This pattern aids in correcting the beam wavefront using a deformable mirror equipped with actuators.
Another significant patent is the "Adaptive optics system using wavefront selection." This optical system is designed to correct wavefront aberrations of an optical beam. It utilizes a reference beam taken from a small portion of the main beam to ensure that the temporal coherence of the reference beam wavefront is substantially in phase. The system employs a beam splitter to create two separate beam paths, allowing for the detection and attenuation of portions of the main beam that are out of phase with the reference beam.
