matrIQ-Doppler™ – Photonic Doppler Velocimetry

Coherent Solutions’ matrIQ-Doppler™ enables Photonic Doppler Velocimetry in a compact and versatile benchtop form factor.

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 a well accepted technique used to measure high-velocity events at speeds up to tens of km/s.

The matrIQ-Doppler combines the key optical components for PDV measurements in a compact instrument to enable streamlined low channel count PDV test setups.

This product comes with a 3 year warranty.


Ultra Compact & Portable Design

Our matrIQ range of compact USB and Ethernet instruments are designed to be portable and versatile,without sacrificing performance.

With a stackable and well-balanced design, they make it easy to stack vertically and save valuable bench space. Plus, when the matrIQ instruments are not being used for PDV measurements, they can be used individually for other purposes in the lab.
