ON THE FIDELITY OF HIGH-SPEED PHOTOGRAPHIC SYSTEMS FOR DYNAMIC PHOTOELASTICITY

A GENERAL THEORY HAS BEEN DEVELOPED WHICH PREDICTS THE INFLUENCE OF THE CHARACTERISTICS OF A HIGH-SPEED RECORDING SYSTEM ON THE FIDELITY OF A DYNAMIC PHOTOELASTIC-FRINGE PATTERN. THE GENERAL THEORY WAS APPLIED TO RECORDING SYSTEMS CURRENTLY EMPLOYED IN DYNAMIC PHOTO-ELASTICITY WHICH INCLUDE THE HIGH-SPEED FRAMING CAMERA, THE SPARK-GAP CAMERA AND THE Q-SPOILED LASER SYSTEM. EQUATIONS FOR A NONDIMENSIONAL FORM OF THE EXPOSURE AS A FUNCTION OF A NORMALIZED POSITION HAVE BEEN DEVELOPED FOR EACH OF THESE THREE RECORDING SYSTEMS. FROM THESE EQUATIONS, CRITERIA TO MEASURE THE FIDELITY OF THE RECORDING SYSTEMS WERE ESTABLISHED. THE METHODS DEVELOPED ARE APPLIED TO THE SPARK-GAP SYSTEM AND EXAMPLES OF RESOLUTION LIMITS, TIME SHIFT, AND DISTORTION ARE ILLUSTRATED. /AUTHOR/
