Abstract Partial derivatives of displacement are optically determined by superimposing two shifted holographic reconstructions which correspond to single components of displacement. Two different methods are proposed, one of which involves shifting a holographic-moiré pattern on itself. A second method takes advantage of holographic multiplexing techniques to incorporate an initial pattern into the shifting process. The latter facilitates the formation of the moiré corresponding to strain information. This paper demonstrates that either method of obtaining derivatives is feasible by documenting an investigation of a disk subjected to diametral compression.
