A1040 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.
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.
The tomograph represents fully-autonomous measurement unit for collection and tomographic processing of the data obtained. Measurement unit contains a matrix antenna array from 48 (12 blocks, each containing 4 elements) law-frequency broad banded transducers of shear waves with dry-point-contact and ceramic wear resistant tips. Hence they can work with rough surfaces for the long time. Each transducer is equipped with an independent spring suspension, thus allowing inspection on the uneven surfaces. Nominal frequency of the array is 50 kHz.
The instrument allows data transfer to the external PC for advanced processing by means of the dedicated software
Inspection is carried out as step-by-step sounding of the testing object with data combining and volume reconstruction over the whole scanned surface of the testing object.
Inspection of concrete constructions up to 2500 mm thickness for the purpose of evaluation of consistency of the construction.
Inspection of reinforced concrete constructions up to 800 mm thickness for the purpose of evaluation of consistency of the construction.
