MultiX Parallel Phased Array Systems

The MultiX product line allows full parallel phased array acquisitions with a total number of 32 to 256 parallel channels, covering a large number of industrial applications. These systems can be operated with virtually all commercially available phased array transducers, in particular linear and matrix type transducers. All standard test methods are supported, such as pulse-echo and transmit-receive mode, TOFD and dual element measurements.

As full parallel systems, the MultiX instruments can send and receive simultaneously on all elements of the array transducer. Data processing and signal reconstruction are accelerated by the integration of specific hardware capabilities such as PowerPC or FPGA chips. The hardware acceleration is particular useful when working in the full matrix capture (FMC) mode, as well as in automated online testing.

The Multi2000 software allows system configuration, performs the data acquisition and displays of the collected data in many different ways. It features a build-in CIVA module, for beam simulation, establishment of the delay laws and calculation of the focus settings. The application of the auto-focusing algorithm developed by CEA allows simple, fast and accurate analysis of samples with varying geometry along the scan line.

Remote control software is provided which allows to control the MultiX system when build into an automated device. Full system control via Ethernet is possible, and the measurement result output can be done in synchronization with an external device.
