Figure 2: Experimental results for the simultaneous imaging of magnetic field and temperature distribution.

From: Simultaneous imaging of magnetic field and temperature distributions by magneto optical indicator microscopy

Figure 2

(a) Illustrations of the printed circuit board (PCB) with the magneto optical indicator (MOI) used as the device under test (DUT). The yellow parts indicate patterned conductor (material: copper; thickness: 20 μm), green parts indicate the substrate (material: FR4; thickness = 1 mm) of the PCB, and a blue rectangle indicates the magneto optical indicator (MOI). (b) Magnetic circular dichroism (MCD) images at 70 ms and 3.5 s after applying an electric current of 7 A to the DUT. The MCD images were calculated by using the eq. (4) from optical images measured by the CCD camera. (c) Line profiles of the MCD images around a region showing an intense MCD signal (indicated by a dashed rectangle in b). (d) Calculated absorption images using by eq. (5) at 70 ms and 3.5 s. (e) Line profiles of the calculated absorption images.
