Abstract

A hybrid optical approach to coherent spectrum analysis realizes gains associated with time-integrating techniques while still retaining some of the advantages of space-integrating techniques. Measurement of large time-bandwidth spectra is performed with high sensitivity, efficiency, and range of detectable signal power levels, particularly in large bandwidth applications, where an optically transformed periodic chirp forms a distributed local oscillator as a reference for time integration.
