Measurement of Turbid Body Optical Properties Using Attenuation of Laser Light Intensity Techniques

  • SK Etana


The main objective of this work was to investigate the laser light interaction with highly diffusing tissue media like milk. In this work collimated  transmission, fluence rate measurements and angular distribution of intensity measurements were made on three types of milks having different fat contents such as fresh cow milk (3.90%), skimmed milk (2.8%) and powdered milk and absorption coefficient.... , scattering  coefficient.... , reduced scattering coefficient .... Œ , anisotropic factor g , scattering particle diameter d and particle size parameter X for different milks were observed. The results of the study revealed that fresh cow milk showed more fat content when compared to skimmed milk and powdered milk. Finally, the fluence rate  measurement methods may be used to test the quality of milk more accurately.
