Infrared imaging allows the versatility and the vast information content of infrared spectroscopic techniques to be brought to bear on the chemical characterization of a large variety of ”real-world“ samples, ranging from biological tissue and cells to manufactured products. In this chapter, the ways in which infrared images are acquired, processed, and interpreted are discussed, with a particular focus on FT-IR imaging microspectroscopy using MCT focal-plane-array detectors. Four categories of infrared imaging applications are presented to illustrate the present and future scope of this relatively new and rapidly evolving technology. Keywords: ATR imaging; chemical image; focal-plane array; FT-IR; high-throughput analysis; hyperspectral data; IR microspectroscopy; linear array detector; multichannel detector; near-infrared; NIR |
