DopplerPXIe – Photonic Doppler Velocimetry Module

The DopplerPXIe is a revolutionary PXIe optical module that enables compact, inexpensive and robust Photonic Doppler velocimetry.

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).

With the new DopplerPXIe optical module, we can provide the necessary equipment to perform reliable, repeatable measurements for simple or multiplexed PDV experiments.

The DopplerPXIe supports traditional homodyne and frequency-shifted heterodyne PDV testing.


accurate power controlAccurate control and measurement of target, probe and reference power.

All of your optical power management in a single-slot PXIe module. This purpose built DopplerPXIe module streamlines your PDV test setup.

reliable resultsGenerate reliable, repeatable measurements.

Minimise the number of manual optical connections necessary with the all-in-one optical doppler module for reliable and repeatable measurements, every time.

multi-channel systemsEasily build scalable, multi-channel systems.

A high channel count PDV measurement setup is now possible. Combine with the LaserPXIe and O2EPXIe modules and fit up to 8-channels in a single 18-slot PXIe chassis.

 small footprintDrastically reduce the footprint of your test setup.

Replace the stack full of bulky individual optical test instruments with one small PXIe module and save your valuable lab space.
