Abstract

A process and apparatus are disclosed for the automatic examination of eggs for cracks or fractured surface areas in their shells. The process includes the steps of directing light from at least one light source onto the egg, and detecting and measuring the intensity of the light emanating from the egg. Cracks or fractured surface areas in the egg shell will allow a greater intensity of light to emanate from the egg. Such relatively higher intensity is measured to determine if a crack or fracture exists. The apparatus consists of at least one light source, a device for rotating the egg, apparatus for moving the light beam over the surface of the egg shell, and a device for detecting the intensity level of the light emanating from the egg.
