Estimation of light transport parameters in biological media using coherent backscattering

Abstract: The suitability of using the angular peak shape of the coherent backscattered light for estimating the light transport parameters of biological media has been investigated. Milk and methylene blue doped milk were used as tissue phantoms for the measurements carried out with a He-Ne laser (632.8 nm). Results indicate that while the technique accurately estimates the transport length, it can determine the absorption coefficient only when the absorption is moderately high (« ½ cm ½ ) for the long transport length… Show more

“…At 1064 nm, milk has an absorption coefficient near 0.02 1∕mm and a scattering coefficient of 7.0 1∕mm. 37,38 It has a lower anisotropy coefficient of 0.7 36,37 and an index of refraction of 1.34. 38,39 The absorption 41 and scattering coefficients 29,31 of gelatin were approximated with the properties of water.…”

“…Using the above technique, we calculated g Ϸ 0.7 for skim milk, which matches well the values reported in the literature. 13 Figure 2 shows the measurement and fitting result for skim milk illuminated from 30°. For the skim milk we used = 1.3485.…”
