Paper Abstract

This photography involves applications in the millisecond to microsecond region. A good focusable camera is aimed at the object to be filmed. Upon operating the camera shutter, the shutter opens and the camera's flash contacts close. A special high current (approximately 1000A) pulse controller is activated which pulses a circuit breaker sample (or assembly) with exposed (or can be viewed through clear plastic) moving parts. At the same instant (i.e. commencement of the pulse) the first flash gun is fired and thereafter the remaining flash guns (5 total ) sequentially. Control of these flash guns is by means of a special custom built controller. The photograph will show the "moving object in several fixed positions". A variety of information can be calculated from this photograph.
