摘要：We developed and characterized a new near-infrared hyperspectral imaging system. The systemconsists of a charged coupled device and liquid crystal tunable filter, which is continuouslytunable in the near-infrared spectral range of 650-1100 nm with a mean bandwidth of 5 nm.Experiments are conducted to quantitatively determine normal tissues characterization. In thefirst experiment, hyperspectral images are acquired from normal lung tissue phantom andanalyzed. The data shows obvious peak absorption intensity at four different near infraredwavelengths (760, 805, 905, and 970 nm). In the second experiment, the simulated malign lungtissue phantom is used to compare the spectrum between normal and malign tissues. Theexperimental result indicates that for different type of tissues, the absorption intensity of thespectrum integrated over near-infrared spectral region was considerably different in normaltissues and simulated malign tissues. This difference provides the basis for the detection anddelineation of the malign tissue margins from the normal tissues.
