An improved technique for high-speed photography
D A Senior, C O J Grove-Palmer · British Journal of Applied Physics · 1952
A technique is described for high-speed cine-photography of the phenomena which take place when small explosive charges are fired under water. At the same time, the explosive pressures are recorded by piezo-electric technique. Pressure records are obtained for a period of 60 msec, and high-speed photographs taken by means of a 16 mm Fastax camera at speeds up to 4 000 frames/sec. At the maximum speed, a cine record in black and white or colour is obtained for a period of 80 msec. The layout of equipment is described, and details of time marking and sequence timing arrangements are given.
