Pierre Slangen is Professor at UMR EuroMov DHM, Univ Montpellier, IMT Mines Ales (France) and co-leads the Computational photography and Virtual reality facility.
Born in Belgium in 1965, he received in 1995 his State PhD in Physics from University of Liege, Belgium.
Since more than 20 years in IMT Mines Alès, he is mainly working on holography, speckle, interferometry, and digital photographic techniques. Prof. P. Slangen is involved in coupling holographic and speckle techniques with high speed imaging for time-resolved measurements of fires, explosions, shockwaves or hypervelocity impacts. Open air large scale measurements of refractive index have also been carried out by shadowgraphy and BOS (Background Oriented Schlieren).
More recently P. Slangen joined UMR Euromov "Digital Health in Motion" (IMT Mines Ales, Univ Montpellier) to apply computational photography techniques in motion capture for well being and health monitoring. Keen and simple motion tracking systems and algorithms are investigated to cope with harsh environments and/or low cost solutions. These developments are also compared, calibrated, using commercial up-to-date sytems and algorithms from Qualisys (Sweden).
Prof. P. Slangen is now involved in building the Ales Intelligent Human Metrology (AIHM) facility, to merge keen motion capture, EEG and NIRS, EMG, and ECG with environmental conditions. In particular, sound, light, or health should be determined to assess relevant diagnostics by artificial intelligence from these body data.
