Abstract

Laser holographic-interferometry technique was used to measure the dimensional changes of graphite-fibre-epoxy-resin laminated plates subject to significant changes of thermal environment. A multiple double-exposure scheme based on the principle of varying incident beam angles was used to record the interference fringes covering large temperature ranges on the same film plate. This feature is highly desirable for industrial applications.
