Observation of light rays on absolute geodesic lenses

Area of Science:

• Optics and Photonics
• Materials Science

Background:

• Absolute optical instruments with rotational symmetry, particularly absolute geodesic lenses, are recognized for their perfect light ray imaging capabilities.
• Generalized Maxwell's fish-eye lenses serve as a foundation for exploring novel optical designs.

Purpose of the Study:

• To systematically investigate a series of absolute geodesic lenses derived from generalized Maxwell's fish-eye lenses.
• To construct novel duplex absolute geodesic lenses by combining different half-lenses.
• To experimentally validate the properties of these lenses using 3D printing.

Main Methods:

• Mapping generalized Maxwell's fish-eye lenses with a rational index {p} to create new absolute geodesic lenses.
• Splicing two distinct half absolute geodesic lenses to form duplex structures.
• Fabrication of absolute geodesic lens samples using 3D printing technology.
• Experimental observation of light ray propagation through the fabricated lenses.

Main Results:

• A new series of absolute geodesic lenses has been systematically explored.
• Novel duplex absolute geodesic lenses were successfully constructed.
• Experimental fabrication and light ray observation confirmed the theoretical designs.
• The findings expand the known family of absolute geodesic lenses.

Conclusions:

• The study successfully expands the family of absolute geodesic lenses.
• The developed lenses demonstrate potential applications in classical imaging systems.
• This research contributes to the advancement of optical instrument design.
