Latest Patents

One of her latest inventions is the "Accusto-optic time-integrating correlator for processing broadband." This invention relates to an acousto-optic time-integrating correlator designed for processing broadband Doppler-shifted signals. The invention utilizes a conical lens telescope to compensate for the differences in the absolute values of Doppler shift occurring in broadband signals. A laser light beam is expanded to a sheet beam using a conventional beam expander, which is then split and redirected using a modified Koster's prism. The two sheet beams are directed toward a surface acoustic wave (SAW) device, which contains two tilted transducers. The outputs of the conical lens telescopes are combined with associated unprocessed sheet beams and imaged onto respective two-dimensional photodetectors. This innovative approach also includes three alternate embodiments that demonstrate how a conical lens telescope can improve the broadband performance of prior art approaches that use cylindrical lenses.

Another significant patent is the "Multi-function acousto-optic signal processor." This acousto-optic architecture allows for simultaneous time integration correlation and power spectrum analysis. The process involves expanding and splitting a laser beam into multiple beams, which are then diffracted by acousto-optic Bragg cells. The outputs are processed through various photodiode detector arrays, enabling the resolution of signals and their correlation in a compressed time frame.
