Estimation of Degree of Polarization in Low Light Using Truncated Poisson Distribution

The Degree of Polarization (DoP) a light beam inside medium contains unique information about the medium. 3D imaging techniques constitute an optimal procedure for determining DoP under low conditions, as computational reconstruction process can increase signal-to-noise ratio detected light. definition division by total number photons from sensor. However, photon starved at single time period may be equal to zero. This pose zero problem computation DoP. In this work, we consider truncated Poisson distribution overcome and show that mean value computed goes independently state polarization validity our approach is verified capturing fields test object compute its conditions. formulae derived in work used correct deviation with respect ideal measurements.
