Abstract
Rotating point spread function (RPSF) is generated using a Fresnel zone type spiral phase mask, which encodes the axial position of a point source in the orientation of the point spread function. Microgrid polarimeter is an established technique to determine the polarization signature of an object. In this paper, we propose a new methodology which combines RPSF technique with microgrid polarimetry in order to obtain a joint polarimetric-three dimensional imaging capability. Simulation results are obtained for 3D localization of point sources and estimation of its linear polarization signature using data frames with and without additive white Gaussian noise.
