Optical Processing of Time Varying Pulsed Laser Excited Photothermal Spectroscopy Signals with Matched Filter Smoothing
This research appiles digital and linear incoherent optical signal processing for rapid photothermal signal magnitude analysis. Temporal signals are processed by both digltai and optical matched filtering technlques and compared in terms of their respective signal to ndse ratlos. The optical processlng resuits in rapld repetitive quantitative slgnai estimation. But the optically processed data are not found to compare favorably to those obtained by using conventbnai digital processed signals. The greater constant noise found In the optically processed data Is an artifact of the blased signal processlng technlque utilized In these experiments.
