Asking information about optical application in Civil engineering

Dear colleagues:

I would want to ask you some questions can help me to
find answers related to my PhD thesis. The main
subject of my thesis is to prove possibilities of
speckle interferometry technique as a non-destructive
method to measure the displacement field in structural
element such as shearwalls and building model. For
this purpose I need to know if have you seen the
modeling of structural elements such as shearwalls by
optical techniques.

I also used an electronic speckle pattern
interferometry to measure dynamic Young modulus in
cementitious materials. In this experiment
interferometry technique was combined with
longitudinal resonance method to measure resonance
frequency by using the quantities of fringe that
appear over the specimen. Have American Concrete
Institute reported the Young modulus measurements by
optical techniques, for example: holographic technique
and speckle interferometry technique? Could you
comment the most important advantages and drawbacks
that the ultrasonic method has when is used to measure
the elastic modulus?

I will appreciate any opinion you can suggest me

Best regards

Prof. Rolando Gonzalez-Peña

FMC/TFM

Next 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

Varex Imaging Large Field of View (FOV) Digital Detector Arrays (DDAs)

A larger FOV DDA can reduce the space and volume of the X-ray inspection system on the factory floor
...
, enable faster scanning times, better throughput and better resolution images at a lower dose. Customers can also save time and money. With these benefits in mind, Varex Imaging has designed a family of large FOV detectors (4343HE, XRD 1611, 4343DX-I, 4343CT) for our industrial imaging customers.
