Paper Abstract

Speckle interferometry in the thermal wavelengths range (long-wave infrared, 8-14 μm), combining a CO2 laser and recording with an uncooled microbolometer camera is presented. In this wavelength range specklegrams are affected by the thermal radiation emitted by objects at room temperature. This allows simultaneously capturing temperature and surface shape information about objects. The FANTOM project is based on this concept and an instrument was developed to take advantage of this natural data fusion. It has been used in a variety of nondestructive testing applications where both information are useful, specifically in aeronautical composite structures.
