摘要

We have theoretically investigated the influence of temperature on magnetic field (MF) sensing by using orbital angular momentum (OAM) beams in BGO crystals. The results have shown that the ambient temperature variation of 1°C could lead to inaccurate MF extraction of 0.3mT by 50-mm long BGO crystal. Therefore, the temperature factor should be considered in the MF sensing. Our results may contribu...
