Wideband Rapid Electric Field Measurement with High Sensitivity based on Optical Frequency Comb
Aiming to solve the problem of mutual restriction of sensitivity and measuring speed in traditional broadband electric field measurement, a wideband rapid electric field measurement method with high sensitivity based on optical frequency comb is proposed and the corresponding frequency recovery algorithm is designed. An electric field measurement system consisting of femtosecond lasers, an optical electric field sensor and a high speed digital acquisition card was built, tested and verified by experiments. Experiment results indicated that the sensitivity of the system is better than that of 20mV/m in the range of 1-9.5GHz, and the uncertainty of frequency recovery is within 1MHz, and single measuring time is about 2 minutes.
