The callenge

The Quantum Gravity Laboratory at the University of Nottingham research at the quantum theory of gravity, that means the unification of general relativity and quantum theory. This is a central element and object of research to understand black holes, and the scattering of gravitational waves in their environment. The related theories should be tested in practice.

Although experiements to real black holes are not possible. But there are analogies to the motion of water waves. Therefore, the model should be shown that the amplitudes of water waves become larger as they pass through a vortex. And then the distribution of wave frequencies of Hawking radiation corresponds to that emanates from a black hole.

The solution: highly accurate real-time measurement

For this, water flows evenly in a tank in which there is a hole. In this manner, a vortex is generated whose direction of rotation is known. In the next step water waves are generated, which runs through the vortex. By measuring the amplitude of two consecutive waves you get the required measurement data. For this, you need an extremely accurate and precise real time measurement of the vortex and its environment. Therefore we used the Detect Sensor from EnShape. With this 3d sensor you can also record precise measurement data of a rapidly and constantly changing surface.

All 3D sensors from EnShape use a unique projection method, which concurrent allows a high rate projection and a high light output, unique to 3D sensors with structured illumination.

Compared to other 3D sensors, EnShape’s measurement data have a higher precision. That is why property details and finer differences in height can be detected with the same spatial resolution. This allows the detection of lowest undulations. So twenty 3D recordings can be realized per second without any problems. The observations of wave dynamics and a wave height by 350 micrometers can be detected.

Due to the precision of the EnShape technology describe instead of very many noisy 3D points, very precise 3D points 3D surface. Of it, the post-processing of 3D data benefits significantly and provides highest precision, robustness and performance. Thus, the post-processing of the 3D data is simplified. Additionally, by using performant algorithms the measurement data are processed in milliseconds. So that the 3D data are available in real time. 

Similarly excellent results achieves the Detect sensor for Pick & Place applications.

What our customers say about us

  • „Recently, we were only able to derive 1D-profiles of the surface using a light-sheet method. Experiments with profilometric techniques lacked the precision for our needs. By using the EnShape technology for the first time it is possible to get full-field information of water surfaces with high temporal and spatial resolution.“
