SCOPE OF SUPPLY
Ultrasonic generation
laser & Detector Laser
Two lasers are used for generation and
detection of Ultrasonic beams in the
part. Both of these lasers generate a very
concentrated beam of light but they react
differently depending on the material.
The laser selected shall not damage of the
component, taking advantage of the most
recent developments of this technology
state of the art. In particular, no additional
surface treatment is envisaged for parts.
Interferometer
The interferometer shall extract the
information contained in the detection
laser which is reflected from the part. That
information is coded in phase modulation.
The interferometer translates this phase
modulation into an intensity modulation
that can be measured. Dual cavity
differential CFP is used like interferometer
with a 94% mirror reflectivity.
The photo detector
As part of the detection chain, is associated to the interferometer. The most of the time, a dark surface like the
composites one doesn’t reflect so much light into the collecting system. This phenomenon is also amplified when
we work with high incidence angles. For that reason it is necessary to have an electronic circuit able to reduce the
noise and adjust the gain, obtaining an with very low light level back from the part. The photo detector sensitivity
must be large enough to overcome that constraint.
Acquisition chain
In order to recover data, the analog signal must be
converted into an exploitable digital signal. The system
architecture enssure the traceability between the
different parameters of the A/D converter and the other
elements of the system.
Mechanical system
Architecture can be adapted depending on the
Customer inspection requirements.
Auxiliary Elements
Video, Audio, Protection, safety elemens such the
cell with suitable crystals or the operator area and
Control Station.
