Abstract
Apparatus and method wherein a photographic plate is doubly exposed by pulsed laser illumination to record successive instants in the history of an object under consideration. The doubly exposed plate is then developed and the photograph or hologram is used to reproduce the object in full three-dimensional detail including subtle changes in the object in the form of interference fringes where the hologram is illuminated with continuous laser illumination.
