Rotation of reference frame dependent polarimetric variables for equidistant fisheye lens projections

Area of Science:

• Optics
• Photonics
• Imaging Science

Background:

• Linear polarizers are essential optical components with well-defined effects under normal viewing conditions.
• Wide-angle lenses, such as fisheye lenses, introduce non-normal viewing geometries.
• These non-standard angles can alter the perceived polarization state of light passing through a polarizer.

Purpose of the Study:

• To develop a method for describing the polarization state of light after passing through a linear polarizer.
• To account for the effects of non-normal viewing angles inherent in fisheye lens systems.
• To provide a framework for analyzing polarization in wide-angle optical setups.

Main Methods:

• The study details a method to model the polarization of light.
• It specifically addresses the scenario of observing light through an equidistant fisheye lens.
• The approach considers the deviation from the normal axis of the polarizer.

Main Results:

• A method is presented to accurately describe the polarization state of light.
• This method is applicable even when the light is viewed at non-normal angles using a fisheye lens.
• The findings are relevant for understanding polarization effects in complex optical systems.

Conclusions:

• The described method provides a way to analyze polarization effects in non-standard viewing geometries.
• It is particularly useful for applications involving wide-angle imaging and linear polarizers.
• This work contributes to a better understanding of light polarization in challenging optical configurations.
