Abstract (en)

[origin: WO2008046986A2] The invention relates to a method for detecting at least one structural abnormality in a spherical particle (33) that comprises at least the following steps: passing the particle (33) through at least one induction coil (15); exciting the induction coil (15) in order to generate Foucault currents in the particle (33); receiving an output signal at the terminals of the induction coil (15); and analysing the signal in order to determine whether or not the particle includes a structural abnormality. Several output signals can be received by passing the particle (33) successively through one or more induction coils (15) with different positions of the particle (33), the or each induction coil (15) being excited at least upon each passage of the particle (33) in order to induce Foucault currents in he particle (33).
