Abstract :
A sensing technique, based on time-wavelength spectroscopy and digital signal processing, is demonstrated through the detection of carbon monoxide. The system utilizes a linearly chirped broadband pulse to identify chemical and biochemical spectra. The main advantages of this method are the absence of an optical spectrometer and the possibility of real-time spectral analysis.
