The MIRA 3D is the advanced version of the well-known, state-of-the-art, MIRA Ultrasound Tomographer for depth measurements and flaws detection in elements of concrete structures. It incorporates the Full-Matrix-Capture (FMC) data collection technique and Total Focusing Method (TFM) processing algorithm to compute the data acquired and directly reconstruct 3D images of the reflecting interfaces within the volume of the object below the antenna at each test position. This “true 3D tomography” system provides greater imaging resolution and precision.
For better and faster scan coverage, the instrument can be extended with a second antenna array. This enlarged version is the MIRA 3D PRO.
MIRA 3D is based on the ultrasonic pitch-catch method and uses an antenna composed of an array of advance active dry point contact (A-DPC) transducers with enhanced penetration depth, which emit shear waves into the concrete and receive them. The 4 by 8 transducer array is under wireless control by a powerful smartphone (control unit) and the recorded data are analyzed to create either a 2-D or a 3-D image (for classic linear mode or the newly incorporated matrix mode, respectively) representing the locations of reflecting interfaces of objects within the concrete’s cross section below the antenna. Multiple series of images obtained from a surface scan of the test element can be “stitched” together to create a full 3-D model that can be visualized directly in the screen of the MIRA 3D control unit or alternatively, transferred to a laptop computer that contains the IntroView 3-D visualization software with additional tools to manipulate the 3-D images for interpretation and reporting of test results.
