Abstract:
Methods and apparatus for ascertaining a relative viscosity characterizing a fluid sample. The fluid sample is illuminated through a scattering membrane adjacent to the fluid with broadband radiation. Scattering from particles within the fluid sample characterized by a distribution of characteristic dimensions spanning at least two orders of magnitude is detected, generating a detector signal as a function of depth relative to a specified surface of the scattering membrane at a plurality of temporal delays. A cross-correlation function of at least one of amplitude, phase and intensity of a scattered optical field is derived for a plurality of depths relative to the specified surface. A mean cross-correlation function is then derived for each depth and fit to obtain a diffusion coefficient, from which a relative viscosity characterizing the fluid is derived.

Claim (Index 5):
A method in accordance with  claim 1 , further comprising calibrating a cross-correlation function decay rate relative to viscosity on the basis of a reference fluid of known viscosity.
