Terahertz for NDT Maybe you have already heard about it:
a new type of instruments deals with new capabilities using a "new" frequency band and mysterious things are sometimes reported in popular magazines. It seems to be attractive for checking aircraft passengers and their baggage to detect items unrecognizable with traditional methods. It is now used in Pharma Industry for Quality Control of Pills. Tera-Hertz Recently I a discussed with a researcher of a german research institute the capability to use them for other NDT - he was very sceptical because of some experiements he heard from an other institute of the neighbouring university. Others tell nice stories. Whats your opinion or experience?
Would be interested to hear more about that.
Seems that detectors are now available, but sources still are challenging to design. Bruker Optics on the other hand is already selling systems for transmission testing ...

------------ End Original Message ------------We are using the Terahertz system T-Ray 2000 created by Picometrix. This company worked with NASA to create a diagnostic technique to image voids in the TPS foam on the External Tank. The development work that remains is to improve the ability to focus the electromagnetic energy at different depths in the 8" foam. The time dependence of this energy is critical and requires sophiticated optical switching which makes the system we have rather large and heavy. It is still somewhat portable in the wheeled carts they package it in. The web site is attached.

This system secures a sound condition of train wheels and is thus a significant contribution to rail transport safety. The device was delivered to CAF recently and its use allows the manufacturer to become an approved supplier of rolling stock in Italy, as it meets the demanding homologation standards of this country. \\\\r\\\\n >  NEOS IIINEOS III is Logos Imagings lightest DR system.

As an ISO 9001: 2015 certified company, EKOSCAN is extremely careful as far a material selection and manufacturing processes are concerned. Our probes guarantee our customers the benefits of latest innovations regarding piezo-composite, backing, impedance adaptation layer, etc.
Specific probes for hostile environment: high temperature, high pressure, corrosive environment,etc.
Specific probes designed to fit your specific application: optimization of every parameter to guarantee you the best detection. >  FMC/TFMNext generation for Phased Array UT is here now with FMC/TFM! Have higher
resolution imaging, impr ... oved signal to noise ratio, characterize, size and analyze
defects better with access to several wave mode views and save raw FMC data for
higher quality analysis. Some of the benefits are:
- Beautiful Image! Easier to understand what you're looking at
- Completely focused in entire image or volume
- Much easier to define setups before inspection
- Easier to decipher geometry echoes from real defects
- Oriented defects (e.g. cracks) are imaged better
- See image from different wave modes from one FMC inspection
- FMC data can be reprocessed/analyzed without going back to the field
