Resumen

A multichannel scanning system for magnetic surface imaging composed of 16 magnetoresistive sensors has been developed. A gray scale, from 0 to 255, was used to represent the magnetic signal detected by each sensor when the sample was moved above the scanner. Measurements and calibration were performed using magnetic surfaces with different shapes and samples with similar profiles, but different magnetization intensities. The system was sufficiently sensitive to detect gradients and discontinuities on the magnetic map. The 16 channel images were numerically processed to obtain a smooth representation of the magnetic map using the Lab View™ Image Vision package.
