Digital electronics platform-based supercontinuum light detection for mid-infrared trace gas sensing
Van Zaen, Jérôme
Harren, Frans J. M.
We present a digital platform-based lock-in detection scheme to improve the gas sensing performance of a spectrometer. A numerically-controlled oscillator serves as reference clock to trigger the supercontinuum source and to demodulate the detector signal.
