A semiconductor band-gap optic fiber thermodetector is introduced to detect the electromagnetic safety margin of the electric ignition system. The bridge-wire′s temperature change is detected under the direction of electromagnetic radiation. The induced current of bridge-wire can be obtained by calculate the coefficients of bridge-wire′s temperature rise and current. At last the safety margins of electric ignition system are achieved under the direction of electromagnetic radiation. The experimental results show that the method can obtain accurate bridge-wire current induced in complex EM environment,and also is a reliable one to evaluate safety margins of bridge-wire electric ignition system.
