Abstract

This paper describes a convenient and quick method to determine the reduced scattering coefficient (mu) _s' and absorption coefficient (mu) _a by fitting a theoretical equation to a measured profile R_m(t). It is based on two new principles; one is to adjust (mu) _s' so as to make a new function f(t) be linear and the other is to use a special function (alpha) t + (beta) + (gamma) /t for quick determination of (mu) _s¹. Test results of the new method are given for several samples.
