Hologram interferometry was extended to the study of stresses in fixed two‐dimensional photoelastic models. Application to three‐dimensional slice analyses was explored qualitatively. The process involved a double exposure hologram, whereby the hologram of the model was exposed before and after annealing. Reconstruction of the processed hologram displayed isochtomatic and isopachic interference patterns.
