KIST/PU Infrared and Raman Chemical Imaging of Pharmaceutical Biological Matter

There have been several advances in instrumentation that now facilitate infrared and Raman imaging. Current Focal-Plane-Array (FPA) detectors are very robust and read out quickly for infrared imaging and fast CCD array detectors are now available for Raman imaging. For example, infrared data collection from a 128x128 FPA now takes place in 3 seconds at 4 cm-1 spectral resolution yielding 16384 spectra! Faster PC’s have also greatly facilitated the processing of the resulting data, where evolving factor analysis, neural networking, and other processing methods are readily utilized.
