| 20120038916 | METHOD AND DEVICE FOR CHARACTERIZING MICROSCOPIC ELEMENTS - A method and device is provided for characterizing microscopic elements. A source signal may be chopped by means of microsystems of opto-electromechanical elements (MOEMS), which gives rise to temporal modulation of the excitation signals. The method of characterizing microscopic elements involves propagating a dispersed light source signal, spatially chopping the spectrum of the source signal into at least two excitation signals having predetermined wavelengths λ | 02-16-2012 |
| 20110291492 | VARIABLE-SPECTRUM HIGH POWER ELECTRICAL PULSE GENERATOR, AND FACILITY AND EQUIPMENT OPERATING SUCH A GENERATOR - The present disclosure relates to a high-voltage pulse generator including a “frozen-wave” generation system for generating high-voltage pulses and a trigger system for triggering the pulses, the generation system including a first and a second photoconductor element, wherein the triggering system includes means for generating a laser light beam and means for splitting the laser beam into two laser beam fractions, each laser beam fraction being directed onto a photoconductor element of the generation system, the splitting means being capable of controlling the distribution of the respective powers of the two laser beam fractions as a function of the orientation of the polarization of the laser beam. The present disclosure also relates to a facility comprising multiple high-voltage pulse generators and electrooptic pump-probe equipment operating such a high-voltage pulse generator. | 12-01-2011 |
