  We report ghost imaging of a single non-reproducible temporal signal in the
range of tens kHz by using pseudo-thermal speckle light patterns and a single
detector array with a million of pixels working without any temporal
resolution. A set of speckle patterns is generated deterministically at
radio-frequency rate, multiplied by the temporal signal and time integrated in
a single shot by the camera. The temporal information is retrieved by computing
the spatial intensity correlations between this time integrated image and each
speckle pattern of the set.
