Novel Imaging Techniques

Novel Imaging Techniques

Coupling imaging and spectroscopic technologies with real-time characterization techniques, based on energy/intensity measurements with electromagnetic, optical, acoustic or vibration excitations or chemistry modifications, represents a major step change in materials analysis. Multi-sensor hyperspectral imaging consists of taking measurements in operando conditions using this coupled image acquisition approach.

How novel imaging techniques will revolutionize life, environmental and material sciences

Coupling imaging and spectroscopic technologies with real-time characterization techniques, based on energy/intensity measurements with electromagnetic, optical, acoustic or vibration excitations or chemistry modifications, represents a major step change in materials analysis. Multi-sensor hyperspectral imaging consists of taking measurements in operando conditions using this coupled image acquisition approach.

Leti is currently addressing the following research topics in this field:

  • monitoring  the  behavior  of  various  macromolecular species  in  key  steps  of  a  cell’s  life;

  • developing compact sensors/imagers for multi-spectral bands (from IR to UV);

  • capturing the body/brain signals, with discriminating noise filtering, for therapeutic purposes in the case of neurological diseases;

  • performing multimodal, multiscale in-situ/operando characterizations of advanced materials to reveal structural, compositional and functional features from the µm-scale down to the nm level. Recent examples are Surface-Enhanced Raman Scattering (SERS), Raman imaging/scanning electron (RISE) microscopy in 3D-FIB-SEM, and surface imaging techniques (ToF-SIMS, PEEM, Auger and scanning probes);

  • developing portable CT-scanner and portable ultralow-field magnetic resonance imaging (MRI) systems, using new technologies of emission, detection, or geometries (in the same way as lens-free on-chip imaging facilitates novel microscopy applications);

  • monitoring fabrication/retail processes with on-line quality and safety controls.
