Magnetic Induction Tomography Measurement System Based on a Fixed Point DSP Module

Magnetic Induction Tomography (MIT) is a noncontact method for imaging the passive electrical properties of objects. An array of excitation coils are employed to induce eddy currents within objects placed within the MIT system and an array of detector coils are then used to detect the resulting perturbation of the primary magnetic fields produced by the eddy currents. Measurement of both the detected signal magnitude and phase must be made.
