英文摘要：

Developed system to test the armature motion state of the rail gun, the device uses a fiber optic probe signal receiving section, to avoid strong electromagnetic interference. Describes the test principle, hard- ware portion of the system is designed to complete the armature signal detection and signal processing and multi-channel output.
