We report processing technique in the MO image measurement system. Calibration procedure is not only considered to perpendicular field but also in-plane field. Current density and field profiles are obtained by Biot-savart law and inversion method. We show example of (Gd,Y)1Ba2Cu3O7-δ-BaZrO3 film that have tilted nano rod pinning centers about 13° from the c-axis.
