A network of disdrometers to quantify the small-scale variability of the raindrop size distribution

Alexis Berne, André Studzinski, Joël Jaffrain

Insight into the spatial variability of the (rain) drop size distribution (DSD), and hence rainfall, is of primary importance for various environmental applications like cloud/precipitation microphysical processes, numerical weather modeling, and estimatio ...

Instrumentation for real-time fluorescence lifetime imaging in endoscopy

Hubert van den Bergh, Georges Wagnières, Thomas Stepinac, André Studzinski

The fluorescence lifetime of living tissues is, in certain cases, related to their pathol. state and is therefore of interest for cancer detection. Measuring fluorescence lifetime in vivo during an endoscopic examn. has thus been a challenging objective fo ...

Frequency-domain fluorescence lifetime imaging for endoscopic clinical cancer photodetection: Apparatus design and preliminary results

Hubert van den Bergh, Georges Wagnières, André Studzinski

We describe a new fluorescence imaging device for clin. cancer photodetection in hollow organs in which the tumor/normal tissue contrast is derived from the fluorescence lifetime of endogenous or exogenous fluorochromes. This fluorescence lifetime contrast ...

Clinical imaging fluorescence apparatus for the endoscopic photodetection of early cancers by use of Photofrin II

Hubert van den Bergh, Christian Depeursinge, Georges Wagnières, André Châtelain, André Studzinski

A fluorescence imaging device applied to the detection of early cancer is described. The app. is based on the imaging of laser-induced fluorescence of a dye that localizes in a tumor with a higher concn. than in the surrounding normal tissue after i.v. inj ...

An endoscopic fluorescence imaging system for simultaneous visual examination and photodetection of cancers

Hubert van den Bergh, Georges Wagnières, André Studzinski

We describe the design and performance tested during six years of clinical trials of a fluorescence endoscope for the detection and delineation of cancers in several hollow organs. The apparatus is based on the imaging of the laser-induced fluorescence tha ...
