摘要: A glass fiber sensor for measuring an electrical current, the glass fiber core being a heavy flint glass having its composition modified by the addition to the glass composition of a source of a selected rare earth ion, whereby the Verdet constant value of the glass is reduced without unduly increasing the value of the photoelastic coefficient.

摘要: A method of determining the magnitude of an exceptionally large current which comprises measuring the angle of rotation of polarized light in a magnetic field created by the current with a glass fiber sensor composed of a fluoride glass having a low Verdet constant and a photoelastic coefficient not over about 0.25 (nm/cm)/(kg/cm2).
