Abstract:
1. A system for detecting single-shot pulse contrast characterization, comprising: a correlator for a generating correlation signal from an isolated pulse, wherein said correlator converts said temporal isolated signal into said spatially distributed correlation signal; a spectral filter receiving said correlation signal and filtering light signals having wavelengths different from said correlation signal, a fiber array comprising a plurality of fibers with different lengths for transmitting said correlation signal in parallel forming parallel correlation signals, and a fiber bundle bounding said plurality of fibers at the end thereof for converging said parallel correlation signals, wherein due to different lengths of said fibers, said parallel correlation signals are converted into serial correlation signals at the end of said fibers of said fiber array, at least one fiber attenuators spliced into at least one of said plurality of fibers respectively for attenuating said parallel correlation signals, a detector for detecting said serial correlation signals to produce analog signals, an A/D convertor converting said analog signals to digital signals, and a computer for processing the digital signals for retrieving the single-shot pulse contrast characterization.
