Imaging polarimeters with imperfect optics, such as low extinction ratio polarizers and varying retardance, show minimal signal-to-noise ratio degradation. Angular positioning errors are more critical than optical imperfections in rotating retarder systems.

Area of Science:

  • Optical Engineering
  • Polarimetry
  • Image Science

Background:

  • Imaging polarimeters typically assume ideal optical components with infinite extinction ratios and uniform retardance.
  • Real-world optical elements in polarimeters often exhibit non-ideal characteristics, impacting system performance.

Purpose of the Study:

  • To analyze the performance of imaging polarimeters with imperfect polarization optics.
  • To quantify the impact of degraded extinction ratios and spatially/angularly varying retardance on system accuracy.

Main Methods:

  • Simulated performance analysis of imaging polarimeters under various non-ideal optical conditions.
  • Quantified signal-to-noise ratio (SNR) changes with varying diattenuator extinction ratios.
  • Evaluated the effect of spatially varying retardance and incidence angle variations on system output.

Main Results:

  • A low extinction ratio of 5 for diattenuators results in only a 2.0 dB increase in noise for reconstructed Stokes parameter images.
  • Imaging polarimeter systems can be optimized to accommodate spatially varying retardance.
  • Angular positioning errors in rotating retarder imaging polarimeters are found to be more significant than optical imperfections.

Conclusions:

  • The performance penalty from imperfect polarizers and retarders in imaging polarimeters is less severe than often assumed.
  • Minimizing angular positioning errors is crucial for high-accuracy rotating retarder imaging polarimetry.
