Nuclear contaminated waste must be isolated for up to 10 , 000 years before it is rendered harmless and, at present, bedded salt is the burial in&lium of choice. Bd&1 salt is not, however, considereI to be an erineerir material ; its lorj-term creep properties are recondite. The prcble facir analysts is that new defomation models require experimental verification for which traditional point-by-point methods , such as strain gages , provide inadequate coverage. Fortunately, wholefield optical tecbniques, speckle photography in particular, are amenable to this measurement prcblem. The use of 'speckle' in this novel application
