Polarization-filterless polarization-sensitive polarization-multiplexed phase-shifting incoherent digital holography...

Area of Science:

• Optics and Photonics
• Holography
• Polarization Imaging

Background:

• Traditional holography often requires polarization filters, limiting efficiency and complexity.
• Capturing both 3D structure and polarization state of incoherent light simultaneously is challenging.

Purpose of the Study:

• To develop a holography technique for simultaneous 3D and polarization information retrieval from incoherent light.
• To improve light-use efficiency in incoherent holography by eliminating polarization filters.

Main Methods:

• Utilizing two polarization-sensitive phase-only spatial light modulators to create self-interference holograms.
• Generating polarization-multiplexed holograms with distinct polarization directions.
• Employing phase-shifting interferometry and numerical refocusing for 3D image reconstruction.

Main Results:

• Successfully retrieved 3D images corresponding to different polarization states.
• Demonstrated improved light-use efficiency compared to conventional methods.
• Experimentally validated the proposed holography technique.

Conclusions:

• The developed technique effectively captures 3D and polarization information from incoherent light without polarization filters.
• The method offers enhanced light efficiency and simplified implementation for polarization-sensitive 3D imaging.
