We demonstrate persistent storage, recall, and conjugation of picosecond light signals from various model objects, including a coin, by making use of coherent optical responses in photochemically active media. A simple linear theory of holographic storage and playback of both the spatial and the temporal behavior of the signal field is shown to describe well the experimental results obtained by utilizing octaethylporphin-doped polystyrene at 1.8 K as a spectrally selective recording material.
