30 January 2012 Infrared spectral imaging by hollow-optical fiber bundle
Author Affiliations +
A spectral imaging system based on a bundle of hollow optical fibers transmitting infrared radiation image is constructed. The system consists of an FT-IR spectrometer and a high-speed infrared camera and infrared transmission spectra are obtained by carefully processing multiple interferograms. It is shown that infrared spectral images of a variety of samples are measured by the system. By mapping transmission of the specific wavelengths in the spectrum, existence maps of oil and fat of biological samples are obtained.
