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