The conception and realisation of a prototype 355nm wind lidar return signal simulator capable of simulating the Rayleigh and the Mie return signals is described. The system is based on a commercial dual wavelength 1064nm/532nm diode pumped solid state las ...
Optical Coherence Tomography (OCT) is an imaging technique with high axial resolution in the micro-meter-scale range combined with a high sensitivity allowing for example to probe weakly back-scattering structures beneath the surface of biological tissues ...
A method and apparatus for a fast and automatic setting of the phase locked loop (PLL) output frequency that significantly improves linearity, locking range as well as spectrum purity, jitter and phase noise performances is disclosed. I n one embodiment, a ...
Magnetic triggering of edge localized modes (ELMs) was reported first from TCV in ohmic plasmas showing type-III ELMs. This method, showing successful locking of the ELM frequency to an imposed vertical plasma oscillation, has now also been demonstrated in ...
Injection locking of two DFB semiconductors opens new possibilities to generate effective signals for optical sensing, in order to reach better performances. Pure wave forms can be generated with qualities exceeding those obtained using external modulators ...
Fourier domain optical coherence tomography (FDOCT) is a high speed imaging technique with high axial resolution in the micro-meter-scale range combined with a high sensitivity allowing to probe 3D volumes of weakly back- scattering biological tissues in-v ...
This paper presents a continuous voltage and frequency scaling approach achieving lower transition (both energy and time) overheads implied by changing voltage levels, at a very low power dissipation and silicon area cost for multi-processor systems with i ...
Injection locking of two DFB semiconductors opens new possibilities to generate effective signals for optical sensing, in order to reach better performances. Pure waveforms can be generated with qualities exceeding those obtained using external modulators. ...

Microprocessors are traditionally designed to provide “best overall” performance across a wide range of applications and operating environments. Several groups have proposed hardware techniques that save energy by “downsizing” hardware resources that are u ...
Frequency stabilization is generally performed by using atomic or molecular absorption lines. However, it is sometimes necessary to lock a laser at a frequency located outside of any absorption peaks. In this case, an offset locking configuration is necess ...
