摘要：
A specific absorption rate measuring system (40), a method thereof, and a biological tissue equivalent phantom unit (1) are disclosed.
The biological tissue equivalent phantom unit includes
a biological tissue equivalent phantom for absorbing an electromagnetic wave; two or more electro-optical crystals (3) that are arranged at two or more measurement points in the phantom, the electro-optical crystals having a dielectric constant that is approximately equal to that of the phantom; and two or more optical fibers (10) laid in the biological tissue equivalent phantom for optically connecting each of the electro-optical crystals to an external destination. The specific absorption rate measuring system for evaluating absorption of the electromagnetic wave energy using the phantom unit includes
a luminous source (4) for irradiating a light; a polarization regulator (7) for adjusting a polarization state of the light that is output by the luminous source; an optical-path switcher (9) for providing the polarization-adjusted light to each of the electro-optical crystals one by one; and a specific absorption rate measuring unit (44) for detecting the light reflected from the electro-optical crystal, and for measuring an absorption rate.
