| Abstract: | The measurement of high voltage nanosecond pulse which using coaxial cable is suffered serious electromagnetic interference, and with low measurement accuracy, optical fiber transmission can effectively overcome the defects. The article narrates the principle of photoelectric conversion and optical fiber transmission measruement system, provided the circuit structure of optical transmitter and receiver, using circuit simulation software Multisim to simulate the circuit. The contrast experiment has been done on the designed photoelectric measuement system and coaxial cable transmission measurement system, the photoelectric measurement system has advantages such as: strong anti-interference ability, high measuring precision, long distance transmission with no waveform distortion. |
