Abstract: Measurements of optical parameters of turbid media based on diffusion theory with CCD camera are studied experimentally. The method of zone restriction for the purpose of deterinating diffused reflectance center is proposed in order to improve the precision of optical parameters. In addition,the method of obtaining one-dimen- sional data from the line through incident point of light and diffused reflectance center is proposed so as to increase the efficiency of inverse algorithm. Intralipid is used to verify the methods. The experimental results show that the both methods are feasible.
