Abstract

Pulse portraits are loosely defined as holograms of live subject matter made with a pulsed laser. The first such exposures were accomplished by Siebert in 1968 followed'by Wuerker, Ansley, McClung (one of my supervisors at Hughes, 1973), Higgens, Gregor and others. In 1982 Hans Bjelkhagen produced white light reflection copies of pulsed masters in 8E75HD, 10 x 12 inches. Prior white light viewable copies had been made as transmission holograms by others but these reflection copies were especially impressive. At that time I toyed with the idea of using DCG as a copy medium and a year later began constructing the complete system which is now operational and expanding. Our system is much like the one Hans used initially except that the pulse energy is lower and the copying is done at 514 or 488nm as opposed to the 647nm line used in the prior system. Optical configurations differ and are evolving in second and third generation pulse and copy cameras.
