Title: Innovations of David Ernest McClelland
Introduction
David Ernest McClelland is a notable inventor based in O'Connor, Australia. He has made significant contributions to the field of technology, particularly in seismic detection and laser frequency stabilization. With a total of 4 patents to his name, McClelland's work showcases his innovative spirit and technical expertise.
Latest Patents
One of McClelland's latest patents is a "System, device and method for detecting seismic acceleration." This device includes a proof mass and a base that provides sensor acceleration relative to the proof mass based on seismic activity. An optical fiber portion connects the proof mass and the base, providing fiber tension based on the sensor acceleration. A fiber Fabry-Perot interferometer (FFPI) in this optical fiber portion offers an optical characteristic representative of the fiber tension. Additionally, a compensator applies tension to the FFPI to account for temperature changes affecting the optical characteristic.
Another significant patent is for "Methods and systems for frequency stabilization of multiple lasers." This system stabilizes the output frequencies of several lasers by combining their beams using an optical multiplexer. The combined beams are then coupled into a length-imbalanced Mach-Zehnder interferometer (MZI) with an optical modulator in one arm. The output is divided into corresponding beams, which are detected by photo-diodes. The generated electric signals are demodulated and directed to servo-controllers to control the central frequency of the lasers, allowing for individual tuning.
