A1040 MIRA 3D is a low-frequency ultrasonic tomography system suitable for manual and automated assessment of concrete structures.
The instrument consists of a lightweight body with 4 x 8 Active Dry-Point-Contact transducers with integrated pulser-receiver circuits and parallel DAQ.
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.
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.

Aging civil infrastructure made of concrete and reinforced concrete puts new requirements to the quality assurance concepts allowing integral assessment of infrastructural objects. Ultrasonic testing with its unique deep penetrating capability offers substantial opportunities for visualization and evaluation of the internal structure of large constructions.
On the other hand, large dimensions of the inspection objects hinder the evaluation of the inspection results beyond inconclusive single data acquisitions in «local» measurement positions.

The low-frequency ultrasonic pulse-echo tomography is applicable to all heterogeneous materials where "regular" ultrasonic flaw detectors (frequency range 1 – 10 MHz) cannot be applied. The following materials can be considered as "inspectable" by A1040 MIRA 3D:
The ultrasonic tomograph A1040 MIRA 3D can be applied for:
The detection and resolution capability of ultrasonic tomography depends on several factors, such as:
In an "average" case, we can state that for an elongated cylindrical reflector (like rebar), the detectable diameter might be 15 mm, while for a "round air bubble," the detectable diameter might be 20 mm.
Keeping in mind that sound attenuation in concrete depends on material properties, such as aggregate size or density of the ceramic blocks, the inspection range must always be considered as a derivative of the optimal inspection frequency. When using an optimal inspection frequency in combination with a sufficient effective aperture of the ultrasonic instrument, the achievable inspection range can be up to 2 – 3 meters. Advanced signal generation and processing techniques, like using coded excitation sequences (E-Boosting), may double the inspection range of the instrument to up to 4 – 6 meters.
Both available software packages for visualization and analysis of UT data perform three-dimensional image reconstruction, when the scans are collected in so called MAP mode – when equidistant measurement points are distributed over the region of interest. The 3D representation of the UT results by overlapping multiple scans provide the most comprehensive information about the inspected volume.
Pulse echo testing is included in the European standard EN 12504-4 for pulse velocity determination. This is then subsequently included in the standard EN13791 for in-situ compressive strength estimation. Though, there are no international standards for pulse-echo imaging and flaw detection yet. The only available guideline for pulse-echo flaw detection is the German Society for Non-Destructive Testing Guideline B4. It is also covered in a German highway authority guideline for measuring tunnel lining thickness (ZTV-ING Teil 5 Tunnelbau) and ACI 228.2R.
Any void filled with the material having different density then concrete can be visualized and detected by ultrasonic tomograph A1040 MIRA 3D, supposed those voids have sufficient spatial dimensions exceeding the ½ of ultrasonic wavelength.
The image below represents detecting steel rebar of ∅16 mm at 17 mm depth (25 mm to the center of rebar).
The ultrasonic pulse-echo tomography is the most suitable technology for detecting voids, honeycombs, and delaminations even below the several rebar grid. While a dense rebar structure will shield a GPR signal from penetrating deeper into the structure, an ultrasonic pulse-echo signal passes through is able to detect deeper-lying voids.
