Abstract

For its high sensitivity and wide bandwidth, superconducting quantum interference device (SQUID) has great advantages in many applications, such as biomagnetism, marine electromagnetic detection, submarine communications, and so on. However, due to the complexity of the environment, the nonorthogonal error of the detection module will have a significant impact on the detection results. Among them, the nonorthogonality of the triaxial module to install sensors is one of the important parameters in the detection system. In this article, the influence of nonorthogonality on static and dynamic sources is given through theoretical derivation and simulation analysis, and the nonorthogonality errors of the triaxial module in one direction were evaluated through experiments using one high-temperature dc SQUID. Finally, the nonorthogonality of the module was derived from the results of the experiments. The way of error analysis in this article may have a guiding role for the future application of triaxial sensors and the evaluation of the nonorthogonality of triaxial module.
