Abstract

A pulsed system for studying forced optical anisotropy, in which a viscous medium flows through a plane convergent channel, is proposed. In this way it is possible to investigate the deformation of the material in pure shear and at high strain rates. The possibility of obtaining characteristic interference patterns, fairly sharp even in the boundary layer, is experimentally demonstrated with reference to the flow of castor oil and a polystyrene solution. The specific possibilities associated with the pulsed operating principle are examined.
