Abstract

While bridgewire electroexplosive device (EED) works in electromagnetic environment, conventional methods can introduce electromagnetism interference. A new method of measuring the induced current in EED is proposed in this article. It bases on infrared imagingto detect the inducting current from long distance and non-contact. The infrared optical fiber image bundle coupling with infrared CCD detector is used to detect the infrared images.At first，the thermal field images are acquired by infrared CCD detector. Then the value of weak induced current of corresponding bridgewire is further determined according to the relations of gray scale values and temperature, temperature and current. The experiment results show that bridgewire current is accurately measured by this method. This method offers a new way to evaluate electromagnetic effect of EED.
