International audience; There is a constant need for direct counting of biotic nanoparticles such as viruses to unravel river functioning. We used, for the first time in freshwater, a new method based on interferometry differentiating viruses from ot

Due to the huge abundance and the major role that viruses and membrane vesicles play in the seas or rivers ecosystems it is necessary to develop simple, sensitive, compact and reliable methods for their detection and characterization. Our approach is

There is a huge abundance of viruses and membrane vesicles in seawater. We describe a new full-field, incoherently illuminated, shot-noise limited, common-path interferometric detection method that we couple with the analysis of Brownian motion to de

Many proofs of concept studies have established the mechanical sensitivity of functionalized microcantilevers to a large spectrum of target molecules. However, moving to real-life applications also requires the monitored mechanical effect to be highl

Infrared lock - in thermography for surface defect imaging in metals for industrial diagnosis

Autor: Y. Fedala, C. Boué, Jean Paul Roger, M. Streza, G. Tessier

Publikováno v: Proceedings of the 2014 International Conference on Quantitative InfraRed Thermography.

Optical lock-in thermography is exploited for qualitative assessment of surface cracks in metallic samples. In order to identify and localize a surface defect, a special image processing of the recorded IR amplitude sequence is proposed. The obtained
