Amplitude-Independent Photonic Instantaneous Frequency Measurement With Improved Sensitivity
A technique for improving the sensitivity of a class of broadband RF photonic instantaneous frequency measurement (IFM) systems is proposed and practically demonstrated. The technique utilizes lock-in amplification to isolate the desired signal from background noise. The demonstration is conducted o...
