Abstract

A closed loop d.c. field fibre optic magnetometer is described which utilises the dependence of the a.c. magnetostrictive responsitivity of a metallic glass sensing element on the local d.c. field in order to detect low frequency or d.c. changes in the total local field. A detection sensitivity of ti 1 μGauss has been demonstrated at frequencies below 2 Hz.© (1984) COPYRIGHT SPIE--The International Society for Optical Engineering.
