Abstract

It has been suggested that the optical scattering effect in a heterodyne acousto-optical system can be ignored because its beat frequency with the reference beam is outside of the IF passband of the heterodyne detection. Our analysis concludes that this is not true. A finite point spread function convolving with the reference beam of a heterodyne spectrum analyzer causes mixing of photons with different frequency shifts and thus generates IF noise. A signal beam with finite scattering level also contributes to optical cross-talk by mixing with scattered reference beam. This problem is made clear below by analytical derivation and experimental data.
