A reel-to-reel Hall sensor array system was build and an inverse operation algorithm was applied to obtain the lateral distribution of critical current density by the remanent field around the superconducting tape. Simulation analysis was conducted to verify the validity of the algorithm. Commercial YBCO and Bi2223 tape and YBCO tape with artificial defects were measured. The standard deviation of lateral critical current density on the cross section of conductor was used as a parameter describing the lateral inhomogeneity of critical current density. The result shows that this measurement method is a stable and efficient way to evaluate the lateral inhomogeneity of critical current of high temperature tapes.
