Double-exposure digital holographic interferometry is a powerful and widespread technique for fine measurement of the induced changes in special physical properties, like density, refractive index and etc. In this paper, application of this technique for measuring the absorbed dose from an electron radiation source in poly (methyl methacrylate) material is studied through modeling. The method of applying this technique for interpretation of the resulted fringe pattern and obtaining the pattern of isodose regions and the percent depth dose curve, that are ubiquitously used for treatment planning and monitoring of the absorbed dose, is investigated. Our results prove the capability of this optical technique for online monitoring of the absorbed dose from a radiation source through interpreting the formed fringe pattern.
