Detailed Documentation

Based on three polarization images acquired by rotating a polarizer to three distinct angles, we can perform detailed calculations and analysis. Firstly, we can compute and generate a Degree of Polarization (DoP) image, which visualizes polarization intensity across different regions using intensity variations from polarized images. This typically involves calculating DoP = √(Q² + U²)/I where I, Q, U are Stokes parameters derived from the three measurements. Secondly, we can calculate and produce an Angle of Polarization (AoP) image that displays polarization orientation patterns using the formula AoP = 0.5·arctan(U/Q). Finally, we can compute and visualize Stokes parameter component images (typically S0, S1, S2) that represent polarization states through linear combinations of the original images. These additional calculations and images provide comprehensive insights into polarization characteristics, enabling quantitative analysis of material properties and surface features. Implementation commonly involves matrix operations on image stacks and trigonometric calculations for polarization vector reconstruction.
