With the steadily rising use of Phased Array inspection methods in industrial applications a fast growing need for ultrasound inspection devices implementing conventional Phased Array processing (hardware based focusing) as well as software based techniques (e.g. Sampling Phased Array, Total Focusing, Full Matrix Capture) arises. At the same time single channel inspection systems are also still demanded. Both types of systems are required to offer high performance, scalability according to the inspection’s requirements and ease of integration into the customer’s infrastructure.

The OPTUS / ETHUS platform, developed by Fraunhofer IZFP, forms a modular and scalable multi-channel inspection system which is able to operate in conventional Phased Array mode as well as in multichannel mode with synchronous channels an also in a mixed-mode configuration, thus covering the whole spectrum of requirements. All modes offer numerous possibilities of hardware based data processing (gates, TD, A-Scan) and the ability of positional triggering of the system. Integration into customer-specific hard- and software infrastructures is simplified by support of different data interfaces and the systems versatile software driver layer (ITK).



OPTUS / ETHUS is optimized for industrial use in automated inspection applications that request phased array functionality and/or a large number of single channels at concurrently high repetition rate of the inspection cycle.


The sturdy frontend design complements the default 19“ chassis variant with a solution for near-sensor assembly. The integration toolkit simplifies the embedding into customer-specific inspection systems by support of established software frameworks (C++, C#, LabView).
