Optical fiber sensors based on surface plasma technology have many unique advantages in specific applications such as extreme environmental monitoring, physical parameter determination, and biomedical indicators testing. In this study, we first utilize a high-spatial-resolution distributed fiber-optic sensing technique based on optical frequency-domain reflectometry (OFDR) to achieve spatially continuous measurement of the neutral gas temperature in a low-pressure Ar ICP discharge. In this paper, we assess the effect of cryostat bridge vibrations on the plasma current measurement accuracy when using a fiber optic current sensor (FOCS) in ITER. Furthermore, many special novel optical fiber structures reported in recent years are.
