Ultra Sensitive Metal Detector

This project, an ultra sensitive metal detector from 1989, uses a magnetostrictive material that changes shape by a small amount in the presence of a magnetic field. By wrapping a fibre optic cable around this material small dimensional changes can be detected by the changes in lenght of the fibre optic cable.
