Abstract

A Stokes camera measures the polarization state as a function of position. We present an interferometric
method to evaluate the spatial resolution of the Stokes camera (Photonic Lattice WPI 200). A polarization
interferometer is used to create spatial variation of polarization states with different spatial frequencies. We
apply Fourier analysis with a Hann window to the signal obtained from the polarization interferometer.
The contrast of recorded polarization fringes is analyzed as a function of spatial frequency.
