摘要：
Fibre-optic diffuse reflectance spectroscopy offers a method for characterising phantoms of biotissue with specified optical properties. For a commercial reflectance probe (six source fibres surrounding a central collection fibre with an inter-fibre spacing of 480 mm; R400-7, Ocean Optics, USA) we have constructed a Monte Carlo based lookup table to create a function called getR(mu(a), mu(s)'), where mu(a) is the absorption coefficient and mu(s)' is the reduced scattering coefficient. Experimental measurements of reflectance from homogeneous calibrated phantoms with given optical properties are compared with the predicted reflectance from the lookup table. The deviation between experiment and prediction is on average 12.1 %.
