Ultra-High-Speed Flash Cinemicrograph

Abstract

The principles of Cranz‐Schardin flash cinematography are described. This method uses up to thirty separate lenses and air sparks to produce an equivalent number of ``still'' photographs. The framing rate and exposure times are determined by the characteristics of the light sources; framing rates of over one million per second have been reported. A modified version of the Cranz‐Schardin camera which uses only one microscope objective lens and eight air sparks to produce eight micrographs is described. The performance to be expected and some possible applications are discussed.
