Patent FR-2526546-A1 (FR)
Inventor: HORST-ARTUR CROSTACK
IPC: G01N29/06
Filed: 1983-05-10
Abstract: The invention relates to a method and a device for detecting faults in the interior of bodies, the fault region to be imaged being irradiated with ultrasound on which a reference beam is superimposed after reaction with the fault, after which the interference field produced in this way is detected holographically, reconstructed and evaluated. The invention has made it possible to apply this method even in the case of thin and sound-scattering materials, with improved resolution and tracing of the shape of the fault and detection of the deformation behaviour of faults. The invention comprises applying a loading to the fault region to be investigated and irradiating said region with ultrasound pulses at at least two different points in time, with an extreme value of the loading in each case. The ultrasonic pulses are short compared with the oscillation time of the loading and, after reaction with the fault, have reference pulses superimposed on them, after which the holograms of these irradiations are superimposed to produce an interferogram which can be evaluated. The block circuit diagram of a device according to the invention is shown in Figure 1, 1 being a loading unit, 3 an ultrasonic emitter and the units 11 - 15 being a control assembly.
