Abstract

We have built a compact and mobile holographic camera capable of recording holograms by double exposure, the time lapse between the 2 laser impulses (duration 20 ns, energy 100 mJ approx.) being adjustable from 0.1 is to infinity. The successful "in situ" experimentation of this device took place during a stay in the facilities of the Aerospatial Company at Suresnes on test bars of aeronautical structures being tested for fatigue (periodical tensile stress).
