Abstract: A device to analyze or reconstruct one or more signals Ij coming from one or more light sources, comprises: means to separate the signals Ij into at least two signals Ij1 and Ij2, at least two channels V1, V2 respectively possessing a gain G1, G2 and a dynamic range D1, D2, said channels having at least one sensor and being adapted to obtain, at output, a signal I′j1, I′j2 with amplitudes Aj1(t), Aj2(t), a device for the processing of the signals I′j1, I′j2 adapted to memorizing the amplitude Aj1(t), Aj2(t) of at least one of the two signals I′j1, I′j2 when I′j1 and/or I′j2 is below a threshold value Smax and to determining the amplitude Aj(t) of the corresponding signal I′j. Streak camera with wide range of amplitude.

Abstract: Multiplexers and demultiplexers including sampling gates in the form of diode bridges are disclosed. Plural-input gates, each formed from two or more diode bridges with two adjoining arms in common, are utilized in a multiplexer designed to synthesize a multi-level output train from a number of binary input trains exceeding the number of gates.
