A novel method to incorporate an optical Hilbert transformer with an all-optical photonic instantaneous frequency measurement system is proposed and demonstrated. Two orthogonal measurements of an RF signal are obtained which enables determination of both signal frequency and power. This system produces DC outputs that simplify the receiver and reduce cost. The system is demonstrated between DC and...
A novel technique for instantaneous frequency measurement using all optical mixing with multiple simultaneous and parallel measurements is demonstrated. This technique requires no special selection of optical wavelengths and provides a systematic method to extend the systems to multiple measurements with only modest increment in component count.
