1. A method of determining the amounts of first and second non-immiscible components in a mixture having known, different indices of refraction in the mixture comprising:
- a) passing a focused light beam through the mixture;
b) measuring the displacement of the actual point of focus from a known focal point through a material with a known index of refraction; and
c) calculating the amounts of the first and second components present from the displacement.

Abstract
Apparatus and method for quantifying the biological components of a biological system having at least two different refractive indices through detection of wave front distortions. The biological component fractions are determined based on information gathered on their respective indices when exposed to particular wavelengths of light.
