Abstract

A fiber-optic sensor has been developed to measure the lightening current. The lightening current which induces birefringence in a glass loop is to modulate a linearly polarized optical beam ((lambda) equals 0.85 micrometers ). The modulated optical information is transmitted to a PIN through an optical cable and converted to the electrical signal. A high-speed data acquisition system is used to sample the pulse signal. The waveform, rise time, peak value, and frequency components of the pulse signal can be shown on the screen of the computer.
