Mira 3D - Ultrasonic pulse-echo tomograph
Pulse-echo tomography systems
Thickness measurement, rebar & flaw detection.
For quality assessment of concrete structures: thickness measurement, rebar localization, flaw detection with ultrasound.
MIRA 3D is a low-frequency ultrasonic tomography system suitable for manual and automated assessment of concrete structures. Due to its novel A-DPC® sensor technology, the new MIRA provides unbeatable penetration depth, inspection sensitivity, and imaging resolution by implementing three-dimensional FMC / TFM in each instrument position.
Operational advantages
The instrument consists of a lightweight body with 4 x 8 Active Dry-Point-Contact transducers with integrated pulser-receiver circuits and parallel DAQ electronics wirelessly connected to the powerful smartphone that implements image reconstruction and visualization algorithms by means of parallel graphic processor units on-board. This hardware solution allows achieving the highest performance for real-time 3D-TFM imaging.
With special transmitting techniques such as E-Boosting, an outstanding penetration depth has been achieved even by using the instrument's relatively small active aperture. Although, for additional extension of the inspection range arbitrary aperture extension can be utilized by two and more array units in one configuration.
MIRA NEO DESKTOP software for remote unit control and 3D visualization & analysis of Big Data is an essential part of the instrument delivered in the standard delivery set. The open data format for customized developments by the user – for offline and online applications – completes the functional package of this extraordinary instrument.
Exploitation
The ultrasonic tomograph MIRA 3D is the best solution for ultrasonic testing of highly scattering materials, such us concrete and reinforced concrete, stones, rock, composites, ceramics, wood, epoxy, refractory materials. Among others, following main applications can be mentioned as application fields of the instrument:
- Localization of reinforcement rebars and other elements (tendon ducts, anchors, hollow pipes, cables, hollow pipes), also beyond of rebar layers
- Detection of material voids, estimation of their position and size in 3D: cavities, inclusions, honeycombs, cracks
- Thickness measurement by one-side access
- Detection of grouting defects in tendon ducts and grouting couplers
- Assessment of fireproof stones
