Ghost Imaging in Time

International audienceGhost imaging is a technique that allows to construct the image of an object from the correlation of two light beams, neither of which carrying out full information about the object. Extensively studied in the spatial domain for the last 20 years, it has recently been transposed to the time domain where it was demonstrated how the intensity fluctuations of a temporally incoherent laser source can be used to retrieve ultrafast bit patterns. In this talk, we will review our recent experiments on ghost imaging in time, including the possibility of magnifying the temporal object using dispersive to time transformation
