Paper Abstract

The high speed recording of shock waves is presently undertaken by a solid-state, time-resolved holographic interferometer in which spatial frequency multiplexing is used to separate the holographically recorded images. The reference beam is constantly divided into n branches of equal brightness by a stack of suitably graded beam splitters, so that each branch is aimed at the film from a different angle and individually shuttered by an electrooptic light valve. This arrangement allows complete freedom to have any or all of the reference beams reach the film for a given pulse of the laser. The implications of these capabilities for shock-tube studies are explored.
