Abstract
A new rapid optical specific absorption rate (SAR) system is disclosed. The rapid optical SAR system has ability to measure and map the power deposited in a flat phantom or other phantom filled with a transparent simulant fluid. Absolute rates of temperature increase in the phantom by photo thermal techniques are measured. For example, the temperature increase and gradients in the phantom bend the path of a laser beam, which may be aimed at a position sensitive detector. The spatial SAR may be mapped and SAR differences between different telephones and telephone orientations, for example, can be distinguished. The system is non-invasive and non-perturbing of the SAR distribution in the phantom, can measure at locations up to the interior surface of the phantom, and provides thermally-based SAR measurements that do not necessarily require constant calibration.
