Holographic interferometry in the thermal wavelengths range, combining a CO2 laser and digital hologram recording with a microbolometer array based camera, allows simultaneously capturing temperature and surface shape information about objects. This is due to the fact that the holograms are affected by the thermal background emitted by objects at room temperature. We explain the setup and the processing of data which allows decoupling the two types of information. This natural data fusion can be advantageously used in a variety of nondestructive testing applications. © 2014 Optical Society of America.

The increasing use of composites, sandwich and lightweight structures and parts in new airplanes leads to a need of adapted Non Destructive Testing techniques for such new materials. Various NDT techniques are currently used for flaw detection or mechanical characterization during the development of aerostructures. There is a constant need for improved inspection methods; with increased reliability, rapidity of inspection time and of setting up, and userfriendliness. FANTOM proposes the development of an advanced NDT technique which combines thermography and shearography which are non-contact full-field optical techniques well accepted in the aeronautical sector for composite structures inspection. The combination is envisaged on the basis of a unique measurement technique using a single sensor instead of a classical approach combining separate sensors. The innovative idea is to develop a holography/shearography sensor in the spectral range of thermographic camera, say at long wave infrared light wavelengths. The state-of-art of components (laser, optics, camera) working in that thermal range is such that one can now envisage such developments with high confidence. Therefore, FANTOM is highly relevant to the objective AAT.2007.4.1.1 of decreasing aircraft development costs through advanced testing tools and methods to improve cost-efficiency and reduce testing time in laboratory and on-ground tests. The successive phases of FANTOM are the definition of specifications, the conceptual design, the development of the critical segments (optical hardware, new high resolution infrared camera and a specific data processing which allows decoupling of thermal and strain informations), the building of a laboratory prototype and its validation on certified samples, and finally the industrial validation in structural test facilities of Airbus and service partner.

The refurbishing to an energy efficient standard leads to tight buildings (whole envelope: windows, walls, etc.) and affects the indoor climate. In case of refurbishing the inhabitants or users are not adapted to this new situation. Therefore the air exchange rates could be lower than required if no mechanical ventilation is installed or the system performance is not optimised. Then, in trying to increase the energy performance of buildings, the indoor environment quality is often degraded due to the lack of exchange with the outdoor environment. People in Europe spend more than 90 % of their time indoors (living, working, and transportation). In more than 40 % of the enclosed spaces, people suffer from health- and comfortable related complains and illness. Already in 1984 the WHO reported an increased frequency in buildings with indoor climate problems. The complexity of the problem and the fact of building related symptom clusters were later described as Sick Building Syndrome. The main objective of the project is to develop innovative solutions for better monitoring the indoor environment quality and to investigate active and passive systems for improving it. The focus lies on cost-effective solutions to ensure a wide application of the developed systems. The project is based on three main objectives: - Development of monitoring systems (wireless and/or partly wired) to detect insufficient comfort and health parameter. It is foreseen to develop a modular version for allowing normal end users making a quick check of the indoor air quality. - Development of control systems for indoor environments which could be based on passive elements like cost effective photo catalytic materials or PCMs and active systems which control the air flow rates based on the monitoring data. - Modelling of indoor environments for the assessment and validation of monitoring data and to optimise with respect to energy efficiency the control parameters and systems.

We report in this paper our discovery of remarkably excellent pyroelectric performances in the widely investigated, but still not well understood, relaxor-based ferroelectric single-crystalline materials of the solid solution system of Pb(B 1, B 2)O 3 (B 1: Mg 2+, In 3+⋯, B 2: Nb 5+, Ta 5+⋯) and PbTiO 3, which have already been considered as next-generation piezoelectric materials with superhigh piezoelectric effect. Values of pyroelectric coefficient as high as 17.2×10 -4 C/m 2 K and of figure of merit for detectivity of 40.2×10 -5 Pa -1/2 can be produced in the poled crystals specifically in the crystallographic direction along the spontaneous polarization, i.e., the <111> direction in the rhombohedral phase. They show great potential as novel pyroelectric materials for wide applications in infrared (IR) detectors and thermal imagers. Commercialized IR detector prototypes have also been fabricated with the specific detectivity of 1.07×10 9 cm Hz 1/2 W -1, which nearly doubles that of conventional LiTaO 3 single-crystal-based commercialized IR detectors with similar detection mode. The relations among crystal composition, iron doping, orientation, phase structure, domain configuration, and pyroelectric property, as well as between thermal parameters and dielectric properties will also be presented here. They address the physics behind and the IR-sensor application using the strong pyroelectric effect of this complicated but promising family of pyroelectric materials. Examples are given for Pb(Mg 1/3Nb 2/3)O 3-PbTiO 3 (PMNT) and ternary Pb(In 1/2Nb 1/2)O 3-Pb(Mg 1/3Nb 2/3)O 3-PbTiO 3 (PIMNT) systems. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

We describe three different interferometric techniques (electronic speckle pattern interferometry, digital holographic interferometry, and digital shearography), using a long-wave infrared radiation produced by a CO2 laser and recorded on a microbolometer array. Experimental results showing how these methods can be used for nondestructive testing are presented. Advantages and disadvantages of these approaches are discussed. © 2012 Optical Society of America.

We introduce a poling treatment to induce a single domain structure in [111] single crystals of 0.72Pb(Mg 1/3Nb 2/3)O 3-0.28PbTiO 3 (PMN-PT). The properties obtained differ from those known for domain-engineered [111] PMN-PT single crystals. The dielectric, ferroelectric, and pyroelectric properties of this single domain structure are assessed in comparison to polydomain single crystals that were poled by conventional poling treatment. The attributes of the single domain state are a single switching event that reflects in a discontinuity of polarization at the coercive field, a substantially lower dielectric loss (than the multidomain state), and a higher detectivity for pyroelectric applications. © 2012 American Institute of Physics.

Non-destructive testing of components is an important auxiliary process step, not only in post-production but also in regular maintenance. The detection of cracks is currently done by using magnetic particle inspection, which is a decades-old, inefficient and ecologically undesirable process. There is an urgent need in industry to replace this technology with more up-to-date methods that provide fully automatic testing. This project thus aims at the development of an autonomous robotic system for the inspection of metallic and composite parts using thermography. By combining automatic path planning for robots using a process model of thermographic image acquisition and knowledge-based image analysis methods, an inspection robot will be developed that can adapt to new parts within 15 minutes and achieves cycle times in the range of 20-30 seconds. Applications include inspection of metallic and composite parts in the automotive and aircraft industry as well as inspection during regular maintenance, mainly in the aircraft industry, where magnetic particle inspection is often a requirement. Market estimates show a potential of more than 1000 such inspection systems within 5-7 years after the end of the project. Despite a higher initial investment (compared to magnetic particle inspection) the robotic inspection system will save more than 400kEUR after 5 years of operation, thus contributing to a substantial increase in efficiency in these tasks. Furthermore, ecologically undesirable suspensions of magnetic particles that include corrosion-inhibitors can be avoided. The consortium consists of technology providers in robotics, industrial inspection and thermographic cameras and end-users that cover metallic and composite parts in the automotive and aircraft industry. SMEs play a leading role in the project and contribute 60% of the total effort.

Physical Review B - Condensed Matter and Materials Physics | Year: 2011

The structural changes of 0.71Pb(Mg1/3Nb2/3)O 3-0.29PbTiO3 (PMN-29PT) are studied by dielectric and optical absorption and hard-mode Raman spectroscopy as a function of temperature. In addition to the known phase transitions of this material at 100, 110 and 124°C two new transitions at 42 and 60°C are observed in unpoled [111]-oriented PMN-29PT single crystals. The phase transitions are associated with changes of the dielectric and optical properties arising from small changes of the inherent local symmetry. The experimental results are analyzed theoretically and a model for the temperature-dependent rotation of the spontaneous polarization is proposed. The formation of two new low-temperature phases, at least on a local scale, reflect an underlying polarization rotation path being much more complex than currently believed. © 2011 American Physical Society.
