Abstract

Unplanned images recorded within holographic space are of candid interest that can reshape audience definition crossing intellectual boundaries. This paper details three examples of off-axis Pulsed Laser transmission holograms that involve holographic portraits. These are movie director Martin Scorsese, former Royal Photographic Society President Mike Austin and a unique recently discovered early pulsed recording of Nick Phillips together with Anton Furst recorded in 1977. Each example was made when operating conditions for the pulsed ruby lasers were optimum, offering a coherence of several meters time-compressed into 25 ns. This gave rise to not only the portrait capture but also others present during the recording session inside the room. This optimum condition captured more than was intended resulting in images that, until now, have remained un-documented.
