  • Method for dynamic interference pattern testing
    Patent number: 5703680
    Abstract: When the pressure on a reinforced rubber object is varied, weaker portions of the object expand more than surrounding areas of the object. By (a) illuminating the object with single phase monochromatic light which is separated into more than one beam, (b) causing the object to distort by abrasion or expansion, (c) observing the interference patterns on the object as it distorts and (d) analyzing stress patterns revealed by the interference patterns, these physical changes can be detected, recorded and analyzed.
