Plasma Profile Analysis

Developed in partnership with academic and military facilities, TERX 3D is a tailored solution to analyze plasma droplets and streams in up to three dimensions based on X-Ray images.

The challenging experimental setup requires a robust and flexible tool to calibrate the sources and provide accurate measurements on the plasma droplets in order to retrieve their velocity, volume, rotations as well as the estimated 3D position of the impact.

Setup and Acquisition


During a TERX 3D test, a series of X-Ray flashes are used to generate shadows of individual plasma elements, which are then captured on film and analyzed.

Identification of the plasma droplets


On a given film plate, several shadowed lines are visible due to the sequential triggering of the X-Ray sources and their different 3D position.

To be able to compute statistics over the velocity, the volume and the rotation of each plasma droplet, it is necessary to identify each corresponding droplet on the different shadowed lines. Once the operator has identified one reference droplet, all the others are automatically detected and tagged with an incremental number if they are located before the reference one on the film (behind temporally) or a decremental number if they are placed after the reference (in front temporally).


The 3D position of the impact of each droplet projected on 2D planes as well as the energy. The breaking time of the hollowed charge
using the different velocities of each droplet. This is a key parameter for reverse engineering in simulation models. The cumulative length of the blast can be displayed in 2D diagrams.
The experimental setup with the position of the 3D surveyed X-Ray sources and 3D position of the film plate can be represented.
