Figure 2 Optical properties of normal and adenomatous human colon mucosa/submucosa in vitro vary with a change of laser wavelength in vitro.
A: Plots of the absorption coefficients measured in vitro vs wavelength of normal and adenomatous human colon mucosa/submucosa; B: Plots of the absorption coefficients measured in vitro vs wavelength of normal and adenomatous human colon muscle layer/chorion; C: Plots of the scattering coefficients measured in vitro vs wavelength of normal and adenomatous human colon mucosa/submucosa; D: Plots of the scattering coefficients measured in vitro vs wavelength of normal and adenomatous human colon muscle layer/chorion; E: Plots of the anisotropy factors measured in vitro vs wavelength of normal and adenomatous human colon mucosa/submucosa; F: Plots of the anisotropy factors measured in vitro vs wavelength of normal and adenomatous human colon muscle layer/chorion.
