OPTIMEX PDV Photonic Doppler velocimeter is a tool for measurement of velocity-time profiles of moving objects using photonic Doppler velocimetry. It can be used for determination of various detonation properties of explosives as well as for any other tasks where high precision in velocity or displacement measurement with extreme time resolution are needed. Photonic Doppler velocimetry is a method of velocity measurement based on the Doppler Effect in laser light. The actual value of the maximum velocity which can be measured lies typically in the range from tens to several thousand meters per second depending on parameters of the selected data acquisition system. The minimum velocity is not limited. The time resolution of velocity histories can be as high as a few nanoseconds. The measurement is simple and robust with almost no constraints regarding quality of the target surface.



When a sample of a new explosive or explosive mixture is prepared, it is commonly required to describe its detonation properties to make sure that they are consistent with preliminary calculations or reference literature values. The measurement of velocity profiles of explosively accelerated materials can be used for inferring key properties of novel high explosives. Unlike traditional but outdated Hess or Kast tests which are used for relative determination of brisance, PDV allows direct measurement without the need of immediate comparison with standard samples. Compared to the piezoelectric pin or high speed streak camera instrumentation, the OPTIMEX PDV offers dramatically increased measurement resolution. The usage of the OPTIMEX PDV system is not limited to explosives but includes high energy physics, ballistics, construction and engineering.
