The vital demand for contemporary industry of real time NDE sensors is in field operation, which often
surrounded by harsh electromagnetic environment such as high level EMI fields or high level of X-Ray or nuclear
radiation.
Contemporary CCD image sensors are highly vulnerable even for 0.5 volt EMI fields and highly vulnerable for x-ray
and gamma radiation.
The high lever radiation such as 50keV, 100kev, 150keV, 200keV, 300keV, 420keV, is extremely dangerous for human
body. CCD image sensors are vulnerable to that radiation level.
We proposed doped single crystal 3D image sensor for the real time NDE measurement.
Proposed sensor was not vulnerable to electromagnetic field produced by High Voltage Tesla generator and to the high
level X-ray radiation: 50keV, 100kev, 150keV
200keV, 300keV, 420keV.
Vulnerability and degradation of CCD image sensor to 40keV and 50keV
X-Ray radiation was demonstrated and documented.
Opportunity to use that sensor for real time NDE of protective coating layers, under high level radiation and EMI fields
is discussed.
Highly efficient volume reflective, dynamical holographic gratings in doped Ti12TiO20 crystals have been
observed.
We demonstrated doped Ti12TiO20 single,
electro-optical crystal and experimental set up, which
combines high reversibility, small response time, high diffraction efficiency and practically unlimited
number of cycles hologram recording, readout and erasing.
It allows using doped Ti12TiO20 crystal as an attractive diffractive optical element in Dynamical
Holographic Sensor -DHS for metrology applications. The high image contrast of the real time
dynamical holographic interferograms without application of external electric field has been obtained for
non transparent diffuse reflective objects using commercial available CW He-Ne laser.
DHS applications for nondestructive test of the most vital parts engineering constructions to prevent
premature failure have has been demonstrated.
DHS application for visualization of cryogenic fields in the near zone of cryoultrasonic cancer tissue
destructor has been presented.
