| Abstract: | Laboratory-scale experiments with explosive charges in the milligram range are a useful tool to investigate basic blast wave
phenomena and to replicate, to some extent, large-scale explosions. This paper reviews and discusses the optical diagnostics
that can be applied in these experiments and outlines how these techniques can be used to obtain new information about the
propagation and interaction of blast waves. Performance criteria for the required instrumentation are established. Several
examples illustrate the potential and the limitations of this approach to blast wave research.
