In this paper, a precise characterization of focusing beam is performed based on the field distribution measurement and beam reconstruction analysis, in order to enable detailed calculation of focusing beam exposure on the surface of human’s skin. To estimate the influence of the experimental condition, we calculated electromagnetic field with varying parameters such as the distance, incident angle, or the skin moisutre condition. The result suggests that the influence of positioning error or the skin condition is relatively small.
