Use of High-Explosive Flash for Photography by the Schardin System

Louis Deffet, Rene Vanden Berghe

This transparence method makes it possible to obtain photographic records of explosive phenomena which have a considerable destructive effect and a very intense self-luminosity. It consists mainly in replacing the sparks of the Cranz-Schardin method with explosive flashlamps that are located in air rather than in argon. The intensity of the luminous flux supplied by these lamps has made it Possible to arrange recording conditions to eliminate completely the parasitic soft luminosity of the object. The synchronization of the various explosive lamps is assured by the use of a detonating cord. The framing rate can attain 1,000,000 frames/sec with an exposure time of the order of 10-1 μsec per image.
