Fast Tracking of Fluid Invasion Using Time-Resolved Neutron Tomography

Time-Resolved Optical Tomography Instrumentation for Fast 3D Functional Imaging

Detectors for Energy-Resolved Fast Neutron Imaging

Two detectors for energy-resolved fast-neutron imaging in pulsed broad-energy neutron beams are presented. The first one is a neutron-counting detector based on a solid neutron converter coupled to a gaseous electron multiplier (GEM). The second is an integrating imaging technique, based on a scintillator for neutron conversion and an optical imaging system with fast framing capability.

Optoacoustic tomography using time-resolved interferometric detection of surface displacement.

We introduce a minimally invasive technique for optoacoustic imaging of turbid media using optical interferometric detection of surface displacement produced by thermoelastic stress transients. The technique exploits endogenous or exogenous optical contrast of heterogeneous tissues and the low attenuation of stress wave propagation to localize and image subsurface absorbers in optically turbid ...

Time-resolved Spectroscopy Fast Time-resolved Mid-infrared Spectroscopy Using an Interferometer

The development of fast time-resolved mid-infrared (MIR) spectroscopy since the 1980s has provided an effective tool for the study of transient chemical species in dynamic systems.1,2 Interest in this particular spectroscopy stems from the virtual universality of infrared (IR) absorption, the rich molecular structural information contained in the MIR spectrum, and the fast time scale of vibrati...
