Latest Patents

One of Harris's latest patents is an optical system that includes an interferometer designed to enhance performance. This interferometer transmits a beam of electromagnetic energy toward a target, with portions of the reflected beam directed onto a detecting surface. The system utilizes a local oscillator beam to provide a beat frequency signal that can represent target range. The design incorporates a first lens to focus the target-reflected return beam onto a point on the detecting surface, and a second lens to align the local oscillator beam with the first lens. This innovative arrangement allows for the use of a photoconductive detector element, which can be cooled by thermoelectric stacks, eliminating the need for liquid nitrogen coolant and significantly reducing the size and weight of the system.

Another significant patent by Harris involves a method for frequency modulating a CO₂ waveguide laser. This system applies Fourier series components of a triangular drive waveform to achieve improved frequency modulation. By selectively applying the fundamental component to the tuning PZT at one end of the waveguide and the odd harmonics to the FM PZT at the other end, the system enhances the modulation capabilities. The use of a waveform synthesizer, frequency splitter, and amplifiers ensures that the drive signals are applied in proper phase, resulting in a more efficient operation.
