Double-pass axially resolved confocal Mueller matrix imaging polarimetry

Area of Science:

• Optical Physics
• Imaging Science

Background:

• Polarization-sensitive measurements are crucial for characterizing optical components.
• Confocal imaging provides depth resolution, but integrating polarization analysis is challenging.

Purpose of the Study:

• To develop and demonstrate a depth-resolved polarization-sensitive measurement technique.
• To characterize optical stacks using a combined confocal and Mueller matrix polarimetry system.

Main Methods:

• Experimental setup combining a confocal imaging system with a complete Mueller matrix polarimeter.
• Acquisition of depth-resolved Mueller matrices for a stack of linear retarders and glass plates.
• Comparison of experimental Mueller matrices with forward simulations.

Main Results:

• Successful implementation of the first combined confocal imaging and complete Mueller matrix polarimetry system.
• Obtained depth-resolved complete polarization-sensitive data.
• Demonstrated good agreement between experimental measurements and forward simulations.

Conclusions:

• The developed system enables accurate depth-resolved polarization characterization of optical elements.
• This technique offers a powerful tool for analyzing complex optical stacks.
• Validated the system's performance through comparison with theoretical simulations.
