Abstract: Detailed motion analyses represent a powerful tool for studying the characteristics of energetic dynamic events such as hypervelocity impacts and explosions. Techniques for evaluating and correcting systematic errors in rotating mirror framing camera records and for improving data analysis methods have been applied to a Beckman & Whitley Model 300 framing camera. Magnification and distortion errors were determined by photographing a precision grid. Precise inter-frame time variations were determined by measuring the angle of rotation of the framing mirror to within 30″ of arc by a reflected laser technique. The use of fiducial markers, specialized film measurement techniques, and semiautomatic data reduction techniques, have made motion analyses with rotating mirror cameras feasible for a wide range of dynamic event studies.
