This month's issue presents the DGZfP CD-ROM of the annual Conference on NDT which took place from 6-8 May 2002 in Weimar. For faster access to the 96 papers (20 MB) you may order a copy via the DGZfP. Copies of this CD-ROM are in production and will be available soon. Papers of this CD-ROM have been written in German, however, with help of the multi-lingual descriptor search English speaking readers may be able to find their topics of interest as well. Furthermore, some authors have already promised to contribute translations for a future issue. All DGZfP authors are welcome to send their translations to Rolf Diederichs at firstname.lastname@example.org. Also in this issue we are pleased to publish articles of individual authors.
For highly attenuating materials, the performance of the system is critical. The ultrasonic sensors,
the scanning area and the system settings should be flexibly adapted to the test task and the material.
These high expectations are met with the new and modular testing system SONOAIR. With the world’s first air-coupled phased-array UT inspection system SONOAIR we developed a technology that works with up to 4 transmitter and receiver channels with freely configurable square wave burst transmitters as wells as low noise receiving amplifiers.
