- Page 11 ACOUSTIC А1040 MIRA Low-Frequency Ultrasonic Tomograph CONTROL SYSTEMS The measurement unit contains of a matrix antenna array with 48 (12 blocks, each containing 4 elements) low-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.
- Page 12 ACOUSTIC А1040 MIRA Low-Frequency Ultrasonic Tomograph CONTROL SYSTEMS As the antenna array consists of dry point contact transducers, the inspection is conducted without any liquid. The interface ensures the use of laser beams which are projected on the surface of the testing object. Thus, the operator can correctly maintain a shift step of the antenna array while performing comprehensive technical diagnostics of the testing object.
- Page 13 ACOUSTIC А1040 MIRA Low-Frequency Ultrasonic Tomograph CONTROL SYSTEMS The internal rechargeable battery provides for 5 hours of the tomograph operation. The increased charge-discharge cycle enhances reliability of the tomograph for long-term applications. Besides, the tomograph can be powered directly from the AC mains.
- Page 14 ACOUSTIC А1040 MIRA Low-Frequency Ultrasonic Tomograph CONTROL SYSTEMS The tomograph allows to transfer data to the external PC for advanced processing by means of a dedicated software. (Figure 6). The inspection is carried out as a step-by-step sounding of the testing object with data combining and volume reconstruc- tion over the whole scanned surface of the testing object.
