High speed engine gas thermometry by Fourier-domain mode-locked laser absorption spectroscopy
We present a novel method for low noise, high-speed, real-time spectroscopy to monitor molecular absorption spectra. The system is based on a rapidly swept, narrowband CW Fourier-domain mode-locked (FDML) laser source for spectral encoding in time and an optically time-multiplexed split-pulse data ... [Opt.
