Single-shot simultaneous intensity, phase and polarization imaging with metasurface

Area of Science:

• Optics and Photonics
• Metasurface Technology
• Optical Field Characterization

Background:

• Traditional optical imaging methods are limited by bulky components and multiple measurements.
• Metasurface-based (MS-based) imaging offers a promising alternative but often captures only partial optical field information.
• Existing MS-based techniques struggle with arbitrary field distributions and simultaneous three-parameter imaging.

Purpose of the Study:

• To introduce a metasurface-based approach for single-shot optical imaging.
• To achieve simultaneous capture of intensity, phase, and polarization for arbitrary optical fields.
• To overcome the limitations of existing methods in comprehensive optical field characterization.

Main Methods:

• Development of a novel metasurface-based (MS-based) imaging strategy.
• Implementation of a single-shot measurement technique.
• Experimental validation using diverse optical fields with arbitrary distributions.

Main Results:

• Successful simultaneous imaging of intensity, phase, and polarization distributions of optical fields.
• Demonstration of the method's capability to handle arbitrary optical field distributions.
• Experimental validation of the versatility and effectiveness of the proposed MS-based approach.

Conclusions:

• The presented metasurface-based approach enables single-shot, comprehensive imaging of optical fields.
• This method overcomes previous limitations in capturing arbitrary field parameters.
• The technology holds significant potential for applications in advanced imaging and optical communications.
