Photon Doppler Velocimeter.

Available in MATRIQ and PXI platforms
 Photon Doppler Velocimeter

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 high-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).

PDV Frequently Asked Questions (FAQs)

By working with many customers we have compiled a list of Frequently Asked Questions covering PDV techniques and instrument selection.

Example questions:
What velocities can be measured with the sampling rate of my oscilloscope?
What type of tunable laser sources should I choose?
Why are two laser sources needed in a typical PDV system?
Should my PDV setup be heterodyne or homodyne?
