Estimation precision of degree of polarization in the presence of signal-dependent and additive Poisson noises

Blog Article

We address precision of estimation of the degree of polarization (DOP) from the orthogonal state contrast image (OSCI) in the axle stopper presence of both signal-dependent Poisson noise due to useful signal, and additive Poisson noise due to dark current and / or background light.We determine the Cramer Rao Lower Bound and deduce from it figures of merit for DOP estimation.In particular, we Bertazzoni KIN86MOD1XB 86cm Modern Series Canopy Hood – STAINLESS STEEL show that the additive Poisson noise has larger influence on DOP estimation than on intensity estimation when light is highly polarized.
