For coherent light, a saturating photodetector's average current is I=I_max(1-exp(-N/Ñ_sat)); inverting this relation recovers the optical phase in the nonlinear response regime.
The electric currents in D1 and D2 are proportional to the incident photon numbers, which can be denoted as I1 = rN1 and I2 = rN2, with r the opto-electric conversion constant

Optical phase estimation via homodyne measurement in the presence of saturation effect of photodetectors
For coherent light, a saturating photodetector's average current is I=I_max(1-exp(-N/Ñ_sat)); inverting this relation recovers the optical phase in the nonlinear response regime.
