Il est d'usage, dans toute une série de travaux sociolinguistiques, de distinguer deux traditions, deux directions de la politique linguistique d'un Etat. La première, conventionnellement appelée «orientale», pose la diversité des langues et de

The measurement of optical ultrafast laser pulses is done indirectly because the required bandwidth to measure these pulses exceeds the bandwidth of current electronics. As a result, this measurement problem is often posed as a 1-D phase retrieval pr

Sonogram encoding is utilized to measure ultrafast optical pulses at 1550 nm. The optical waveform is divided into narrow-bandwidth frequency bins, which are time multiplexed. The recombined single-shot sonogram signal is acquired using high bandwidt

We demonstrate a combined optical and electronic system for measuring optical waveforms at bandwidths up to 2 THz. The technique uses sonogram decomposition of the waveform to reduce the optical bandwidth to levels measurable with current electronics
