Abstract
A method for detecting blast induced pressure changes includes exposing a material, a contained solution, a membrane-bound solution, or a photonic crystal material, having a first optical property, to a pressure wave having a blast level. A change in the first optical property to a second optical property of the exposed material, contained solution, membrane-bound solution, or photonic crystal material is determined, and the extent of change corresponds to the blast level.
