ABSTRACT:
The viscosity of a fluid material, e.g. a synthetic-resin composition, or the coagulation of blood or plasma monitored by placing a quantity of the fluid substance on a support, directing a beam of light upon the sample, detecting reflected light from the sample and vibrating the support at a given frequency and amplitude to disturb its surface. The reflected light detected is a function of the viscosity or the degree of coagulation.
