Une conférence le 13 février 2025, depuis le Paris-Saclay Summit Choose Science en compagnie de : Elise Colin (ONERA, ITAE Medical Research), et Julien Guihaire, chirurgien cardiaque à l’hôpital Marie Lannelongue, responsable du programme de transplantation cardiaque et assistance circulatoire de la Faculté de médecine de l’université Paris-Saclay Modératrice : Anne Jeanblanc, journaliste au Point

Recently, we unveiled a fascinating capability: the detection of the subtle rhythm of heartbeats across the entire face. In this analysis, we captured a 10-second video sequence of 800 frames (80 Hz). The integration time T is 12 ms. We calculated temporal speckle contrast using a sliding window of 50 frames. A remarkable observation emerged:… Read more: Revealing Heartbeats Across the Face

We are happy to announce the publication of our latest article in Photonics, titled “Standardizing Laser Speckle Orthogonal Contrast Imaging: Achieving Reproducible Measurements across Instruments” https://www.mdpi.com/2304-6732/11/7/585 🔍 For the first time to our knowledge, we demonstrate the reproducibility of measurements on microcirculation between two independent instruments following a simple calibration process, by using the measurement… Read more: Our new publication about the reproducibility of measurements

We obtained a captivating new image of leaf sap circulation using our cutting-edge imaging device.Unlike the rapid blood flow observed in animals, sap circulation in plants operates on a much slower and more variable scale. This slow movement presents unique challenges and opportunities in imaging technology. Our latest advancements allow us to capture these slow… Read more: Leaf sap circulation

During the Journées d’Imagerie Optique Non Conventionnelle (JIONC, or Non-Conventional Optical Imaging Days, 2024 March 14th), Elise Colin and Aurélien Plyer had the opportunity to present, with our colleagues from the LPICM (Razvigor Ossikovski, Enrique Garcia Caurel) a significant stage of our research on the interactions between dynamic speckle and polarization. A critical component of… Read more: JIONC 2024
