Development of the 0.16THz in vivo exposure system for evaluating acute ocular damages with the high power gyrotron electromagnetic wave source

摘要

In this study, a new in vivo exposure system for 0.16 THz exposure has developed to investigate the threshold level of power density inducing thermal ocular damage. To realize this system, the gyrotron FU CW GV was used for the 0.16THz high power EM wave source. When the irradiated power density was 500mW/cm~2, the maximum temperature elevation at 6min from the onset of exposure became 26.4°C and 19.8°C for an agar phantom and a cornea of rabbit eye, respectively. Consequently, we have achieved the sufficient temperature elevation to observe acute cornea damages due to the thermal effect at 0.16THz.
