Invited Speaker / Conférencier invité

Computed tomography (CT) is an inverse problem in which an image is reconstructed from measurements, making use of the forward problem presented by the well-known Beer-Lambert Law for the absorption of a beam of monochromatic radiation. Then, the natural logarithm of the relative intensity of a transmitted beam of radiation leads to a linear problem in the form of a Radon transform, the...

There has been a recent increase in the use plasmonic nanoparticles for biomedical applications, such photo-thermal therapy, optical and optoacoustic imaging, and biosensors. Gold nanoparticles (GNPs) are of particular interest due to their strong plasmon resonances, stability and biocompatibility. Plasmon coupling occurs when GNPs aggregate resulting in a shift of the resonance wavelength....

Fiber-optic sensors based on fiber Bragg gratings have been established as rugged and reliable devices and have found applications in environmental monitoring, oil and gas reservoir monitoring, and in performing temperature, pressure, and strain measurements. However, new sensors with higher sensitivity, greater accuracy, and a simpler design, using fiber laser technology, would provide...
