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