A process for the detection of flaws in an article comprising infra-red scanning of the article as its temperature changes and comparing the infra-red scans for regularity of cooling/heating pattern. Where the article is irregular, such as in marginal areas, thermodynamic modelling is performed to establish a hypothetic cooling/heating pattern for an unflawed article.

Defect detection in articles using computer modelled dissipation correction differential time delayed far IR scanning

A light beam such a laser beam is used to scan the surface of an egg for flaws such as pin holes, cracks, thinned shell regions, etc. The light beam is vibrated with a rocking/rotating movement to describe a closed curve such as a circle, ellipse or an ellipse so narrow that it is effectively a straight line. The utilization of such a light beam allows identification of types of flaws due to the character of the progression of light emanating from the egg. The invention includes apparatus for rotating the egg about its longitudinal axis in the path of the beam or beams. The apparatus also includes apparatus for forming the vibrating beam such as mirrors vibrated by out of phase electro-magnetic vibration or piezo electric actuators.
