Re: NDT Technique in Antiquity or Arcaeology Dear Mr. Hazizi,
Various techniques are available and some are in use in the area of artwork, antiquities, historical buildings etc., mainly variations / adaptations of industrial techniques (such as UT, Acoustic Emission, Acousto-Ultrasonics, Impact Echo, ...), but also specialized methods such as Laser Doppler Vibrometry, hologram interferography, shearography, thermography, etc.). Proper selection depends on the item to be examined, and type of defects seeked. European Community-funded R&D work is currently underway aiming to integrate optimized techniques towards artwork conservation strategies (see http://www.iesl.forth.gr/programs/laseract/index.asp).
If you need further info, you could contact me with

ISAFE3 Intrinsically Safe Sensor System
ISAFE3 intrinsically safe sensor system of Vallen Systeme is especially targeted at the petrochemica
l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications.
The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation.
ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
GEKKO, Standard and Advanced phased-array for Easier inspection
With a 64-channel parallel architecture, GEKKO is a flaw detector
offering at the same time conven
tional UT, standard PAUT, TOFD and
real-time Total Focusing Method (TFM). GEKKO improves the
detection, with better defects characterization
and sizing as well as for misoriented defects.
Some procedures require standard UT, others TOFD or PA. GEKKO
includes all these techniques to offer a versatile and field-ready
- 64:64 parallel channels
- + 4 additional TOFD
- Conventional UT channels
- International code compliance: ASME, AWS, API, ASTM, ISO-EN

Ultrasonic tomograph for imaging of concrete structures А1040 MIRA
Applicable for concrete inspection allowing imaging of the internal
structure of objects from conc
rete, reinforced concrete, different
stones. The operation applies pulse-echo technique at one-side access
to the object. The instrument is feasible for concrete inspection for
searching conduct ducts, conduits, detection of foreign inclusions,
holes, honeycombing, cracks and other concrete defects.
