摘要：

Time-wavelength spectroscopy, using a linearly chirped broad-band pulse, eliminates the need for an optical spectrometer and enables real-time analysis. Utilizing digital filtering and matched detection, we demonstrate identification of gas signatures that are entirely masked by highly nonuniform source spectra.
