- •
We outline a novel model of phase diversity CRx using phase-shifting interferometry.
- •
We propose analytical solution to predict sensitivity degradation for arbitrary phase diversity CRx.
- •
2×4 90° hybrid balanced detection and 2×3 120° hybrid are the best phase-diversity CRx.
- •
We validate the model in experiment.
