Abstract
Application of holography to photoelasticity is briefly discussed, with emphasis on its potential in isopachic stress analysis. A complete holographic interferometer is described. The method of wavefront reconstruction simplifies the optical requirements in conventional two‐beam interferometry. By employing a photochromic recording medium, the technique of real‐time interference becomes a practical and convenient process. Examples of isopachic fringe patterns obtained by this interferometer are shown.Keywords
