Description:

This Master Prompt develops a research framework for using images as experimental measurement records and for monitoring physical changes across space and time. It covers measurement-problem formulation, imaging-system configuration, spatial calibration, acquisition timing, reference images, regions of interest, speckle quality, digital image correlation, displacement and strain measurement, dimensional analysis, crack monitoring, interfacial damage identification, phase-region measurement and process-state characterization. Particular emphasis is placed on connecting the recorded image signal to the quantity being measured and distinguishing direct observations, calculated quantities and model-dependent interpretations.
