Laser Doppler Imaging (LDI) is a non-invasive optical technique used for assessing the blood flow in biological tissue. This technique allows visualizing 2D distribution of blood flow over an extended area of tissue, e.g. human skin. We have developed a ne ...
We present a new method for estimating heart motion from two-dimensional echocardiographic sequences by exploiting two ultrasound modalities: B-mode and tissue Doppler. The algorithmestimates a two-dimensional velocity field locally by using a spatial affi ...
Resonant Doppler Fourier domain optical coherence tomography (FDOCT) is a functional imaging tool for extracting tissue flow. The method is based on the effect of interference fringe blurring in spectrometer-based FDOCT, where the path difference between s ...
Characterizing the transport processes at the sediment-water interface along sloping boundaries in lakes and reservoirs is of fundamental interest in lake and reservoir water quality management. The turbulent bottom boundary layer (TBBL) along a slope, ind ...
We present a combination of topography measurements based on digital fringe projection and blood flow imaging based on Laser Doppler Imaging (LDI). Both techniques are optical, non-contact and high-speed whole-field methods well suited for in-vivo measurem ...
We will present a method allowing to evaluate the mechanical performances (torque, speed, mechanical power, dissipated losses in the surface of contact between stator and rotor) of the travelling wave ultrasonic motors. The visualization of the motor chara ...
After the first two successful editions of the Symposium on Ultrasonic Doppler Methods for Fluid Mechanics and Fluid Engineering (ISUD), held at PSI, Villigen, Switzerland in 1996 and 1999, we are very pleased to organize this third edition for the first t ...
Vibrational sum-frequency generation (SFG) employing femtosecond infrared (IR) laser pulses is used to study the dynamics of the C-O stretch vibration on Ru(0 0 1). Time-resolved measurements of the free induction decay (FID) of the IR-polarization for 0.3 ...
We performed variable temperature (0–100°C), concentration and frequency (9.425, 75, 150 and 225 GHz) continuous wave electron paramagnetic resonance (EPR) measurements on three different Gd(III) compounds: [Gd(H2O)8]3+, [Gd(DOTA)(H2O)]− (DOTA: 1,4,7,10-te ...
Synchrotron light is usually treated with a rather complicated electrodynamics formalism. However. its basic properties can be easily understood with a simple approach based on the classical emission of electromagnetic radiation by an accelerated charge in ...
