Abstract
The operation principle of calorimeters used for dosimetry of ionizing radiations is based on measuring the induced temperature difference in the adsorbent due to thermal energy deposition of the ionization radiation. In recent years, one of these methods has been the holographic optical calorimetry by laser beams. One of the problems that affect the response accuracy of the calorimeters is the heat transfer phenomenon in the adsorbent material. This phenomenon affects the measurement accuracy of the absorbed dose. In this research, a model was developed for the post-processing of camera images of the interferometric calorimeter system with a water phantom under vertical and horizontal irradiation with electron and proton beams.
