Abstract

A method of determining the quality of oriented polymeric materials, based on the effect of small-angle scattering of polarized light, involves the passage of a beam of monochromatic, polarized and collimated light through an oriented polymeric material, extracting the scattered reflections, converting them to a train of electric pulses, and determining the degree of orientation of the material using the pulse spacing. An apparatus comprises a source (1) which produces a beam of monochromatic, polarized and collimated light passed through an oriented polymeric material (2), and a housing which accommodates an analyzer (4) formed of polarising material, a mask (5) and a unit (6) to convert the scattered reflections passed by the mask (5) to a train of electric pulses. The scattered reflection converting unit (6) comprises a scattered light detector (7) coupled to a recorder (8). The apparatus of the invention can find use in chemical, textile and other industries utilizing polymeric materials. <IMAGE>
