Area of Science:

• Optics and Photonics
• Holography
• Imaging Science

Background:

• Incoherent digital holography (IDH) with two polarization-sensitive phase-only spatial light modulators (TPP-SLMs) offers simultaneous 3D and polarization information retrieval without polarization filters.
• However, conventional filter-free polarimetric IDH using TPP-SLMs requires a significant number of exposures (seven), limiting its practical application for dynamic scenes.

Purpose of the Study:

• To develop and describe novel optical designs and modified phase-shifting interferometry techniques.
• To significantly reduce the number of required exposures for filter-free polarimetric incoherent holographic imaging using TPP-SLMs.

Main Methods:

• Implementation of advanced optical designs tailored for TPP-SLMs.
• Modification of phase-shifting interferometry algorithms to minimize data acquisition steps.
• Experimental validation of the proposed methods for reducing exposure count.

Main Results:

• Demonstrated reduction in the number of exposures required for filter-free polarimetric incoherent holography.
• Successful acquisition of both 3D spatial and polarization information with fewer recordings.
• Validation of the proposed methods' effectiveness in simplifying the holographic imaging process.

Conclusions:

• The proposed methods effectively reduce the number of exposures needed for IDH with TPP-SLMs.
• This advancement paves the way for filter-free, single-shot multidimensional incoherent holographic imaging.
• The technique holds potential for applications requiring rapid acquisition of both spatial and polarization information.
