Our team in Seattle did an experiment using an ARAMIS Optical Strain Gage to track the displacement of a toy scorpion as it ran across a desk.

ARAMIS Testing the Displacements and 6-DoF of Mr. Scorpion
Our team in Seattle came across a scorpion that was displaced from his home! Luckily, ARAMIS Optical Strain Gage had no problem measuring its displacements. Using an ARAMIS 12M Adjustable system in "fast mode" at 3 Mpx at 100 Hz, we captured the displacement and the six degrees of freedom (6-DoF) as Mr. Scorpion scurried across the table. The acquisition of the data was done with spray paint, target markers, and the ARAMIS 3D Digital Image Correlation Optical Strain Gage. We sent Mr. Scorpion in the right direction for home, and, in only a couple of minutes, ARAMIS captured incredible data at a much faster rate than foil strain gages. ARAMIS is the perfect tool for measuring High-Speed events with the ability to measure high strain rate, displacement, and vibration for 1K frames per second (fps) to 5M (fps).
ARAMIS Data from Experiment
It is often important to know how the location of the two parts move relative to each other over time. This picture shows the distance change between the tip of the scorpion’s tail and the top of the body over time. We displayed this value as a label and in chart form below it.
Using the surface components created from the speckle pattern, we constructed distances between the start and endpoints of the bottom segment of the tail and the body. We then inspected the angle between these distances to determine how the tail moved relative to the body while the scorpion ran.
Using a target dot on the scorpion’s tail, we can use the coordinate system we defined to inspect the X, Y, and Z displacement of this point over time. The label on the tail shows the current value in each direction, while a plot below the image shows the same information over time.
Join us as we host a webinar with Vision Research, AMETEK the company behind Phantom High-Speed Cameras. Learn the benefits of DIC in high-speed applications as well as the Phantom High-Speed camera line. After the presentation, there will be exciting live demonstrations of ARAMIS, our 3D DIC system paired with Phantom cameras.
Join us at the National Museum of the U.S. Air Force in Wright-Patterson AFB, OH (just outside of Dayton) for our half-day Next-Generation High-Speed Measurement Workshop. This event will showcase how easily you can take high-speed measurements with ARAMIS 3D Digital Image Correlation (DIC) System, including high-speed strain, displacements, and vibration analysis measurements. The workshop will be held in conjunction with the experts at Photron High-Speed Cameras. You don’t want to miss this opportunity to become expert users in the art of High-Speed Digital Image Correlation!
