Latest Patents
Hoi C Sun holds a patent for a "Method and apparatus for reducing fringe interference in laser." This invention utilizes a frequency tunable laser to generate a beam that passes through a sample cell and onto an optical detector. The tunable laser is modulated at a predetermined frequency, which can create periodic interference fringes near an absorption-induced signal. To mitigate this issue, an additional modulation is applied to the laser beam using a triangular waveform with a specific peak-to-peak amplitude and frequency. This innovative approach results in a frequency swing of the laser beam, generating a signal with reduced components near the absorption-induced signal. The optical detector's signal is then demodulated by a lock-in amplifier tuned to a predetermined harmonic of the triangular waveform's frequency.
