Abstract
Description
technical field
[0001] The invention belongs to an infrared spectrum measurement method and a special device for detecting biological tissues in vivo and flexibly monitoring chemical reactions, and belongs to the technical fields of biomedical photonics, molecular spectrum measurement and devices. Background technique
[0002] Attenuated total reflection (attenuated total reflection) technology is a new and widely used infrared spectral measurement technology in spectral testing. Attenuated total reflection technology has the advantages of simple sample preparation and cleaning, no need for pretreatment, no damage to the sample, can measure a small amount of water and small particle samples, can eliminate the influence of light scattering and other factors, the measured infrared spectrum is of high quality, and there is no interference fringe. The characteristic bands are clear and not deformed. With the development and wide application of Fourier transform infrared spectro...
