Low coherence interferometric system; Shearography; 3D profilometry
Abstract :
[en] The present invention relates to a portable industrial instrument for performing, in an integrated and two-way manner, an interferometric fringe projection and shearography, on a object to be tested, so that, when the two-way interferometer is associated with the coherent or quasi-coherent projection device, the instrument is able to measure the 3D shape of the object by interferometric fringe projection, also known as moiré method, and, when the two-way interferometer is associated with the recording or imaging device, the instrument is able to perform shearographic measurements on the object.
