Quantifi Photonics Photonic Doppler Velocimetry PDV instrument

Doppler 1000 Series

The Quantifi Photonics Doppler instrument combines the key optical components for Photonic Doppler Velocimetry (PDV) measurements in a compact instrument to enable streamlined low channel count PDV test setups.

Velocity measurement of fast-moving materials is essential to a growing number of scientific and technical fields including shock physics, the study of material properties, hypervelocity impact testing, detonics and shock wave experiments.

Photonic Doppler velocimetry (PDV) is an established technique used to measure high-velocity events up to tens of km/s. It is also known as heterodyne velocimetry and can be used as a supplementary tool or replacement for Velocity Interferometer System for Any Reflector (VISAR).
