Abstract
A multi-spark camera of a pulse-control type has been constructed. Typical performance of the camera is as follows: number of frames=24, maximum framing rate=1×106 frames/s, full width at half-maximum duration of a light pulse =0.4μs, maximum energy of discharge capacitor=2 joules, light sourced dimension=1mm, and static spacial resolution=6lines/mm. Several examples of photography using the camera have been included, related to a flyer impact test, fracture shadowgraphy of a polymeric material and water eruption due to an under-water spark.
