Abstract :
It has been demonstrated that millimeter waves (MMW) are absorbed by surface tissue, such as skin or cornea. It was shown in our laboratory that damage from MMW exposure was related to heat accumulation and transport. To study the relationship between relative humidity and ocular damage, we investigated the effect of relative humidity during MMW exposure. The ocular temperatures of rabbits were measured during exposure to 40 GHz MMW (200 mW/cm2). To visualize the dynamic change of temperature and distribution in the anterior chamber, 0.2% microencapsulated thermochromic liquid crystal (MTLC) was injected into the anterior chamber of rabbit eye. We showed that low humidity during exposure decreased heat accumulation and transfer.
