High-dimensional one-shot optical field compressive sensing of structured light

Area of Science:

• Optics and Photonics
• Optical Sensing
• Light Field Metrology

Background:

• Traditional light detection is limited in capturing the full dimensions of light fields, such as amplitude, phase, polarization, and wavelength.
• Existing methods struggle to resolve complex structured light, necessitating advanced optical sensing capabilities.

Purpose of the Study:

• To demonstrate a novel concept for high-dimensional, one-shot optical field compressive sensing.
• To enable the resolution of full-dimensional information for arbitrary light fields.

Main Methods:

• Development of a high-dimensional one-shot optical field compressive sensing framework.
• Experimental validation using various structured light fields, including optical vortices and polarized beams.

Main Results:

• Successfully resolved full-dimensional information (spatiotemporal amplitude, phase, polarization, wavelength) of complex light fields in a single shot.
• Demonstrated the capability to sense ordinary and structured light fields with high fidelity.

Conclusions:

• The proposed light detection framework achieves full-dimensional optical sensing of arbitrary light fields.
• This technology has potential for compact, high-dimensional detectors and real-time observation of dynamic optical processes.
