PVDF FILM USED IN THE RESEARCH OF METAL CLEAVAGE

The paper introduces the principle of a synchronoustrigger based on PVDF film. With the input of fast PVDF film and probe, thetrigger can reach the precision of one microsecond. When it is used in metal cleavageexperiment, the flash X-ray digital imaging systemcan be made synchronous, to obtain the X-ray images of metallicchippings at different instants.
