Latest Patents

One of his latest inventions is the multi-beam heterodyne laser Doppler vibrometer. This innovative device simultaneously measures velocity, displacement, and vibration history of multiple locations on an object. The technology involves splitting a beam of coherent light into an object beam and a reference beam. The object beam is further divided into several beams to illuminate multiple locations on the object under inspection. The reference beam is frequency shifted and split into corresponding frequency-shifted reference beams. Each object beam reflects off the object as a modulated beam, which is then mixed with the reference beams to create beam pairs. These pairs can be focused onto a photodetector or an optical fiber connected to a photodetector, allowing for precise measurements.
