Latest Patents

Yifeng Chen holds a patent for a "Chirped laser dispersion spectroscopy sensitivity booster." This invention is a sensitivity-boosted laser dispersion spectroscopy system designed for sensing samples in a sample cell or in an open path crossing the sample. The system features a local oscillator arm and a sample arm that contains the sample cell or the open path. A laser source generates a first light beam directed along the sample arm and a second light beam, which is frequency shifted and directed along the local oscillator arm. An intensity modulator, phase modulator, and frequency shifter are integrated into the sample arm to create a multi-frequency beam with known frequency spacing. This beam is then passed through the sample cell to produce a sample arm output. A beam combiner merges the sample arm output with the second light beam from the local oscillator arm, generating a combined beam. Finally, a photodetector detects the combined beam for effective sample sensing.
