Generation controllable optical chain using an optical pen

Area of Science:

• Optics and Photonics
• 3D Light Manipulation

Background:

• Traditional optical chains lack dynamic control over focal points and spatial arrangement.
• Existing optical manipulation techniques often struggle with complex 3D structures and dynamic transformations.

Purpose of the Study:

• To propose and generate an aperiodic, snake-like optical chain with controllable focal points.
• To introduce self-rotation and 3D twisting capabilities to optical chains.
• To explore applications in advanced optical multiplexing and intricate light manipulation.

Main Methods:

• Development of an optical pen technique for generating aperiodic optical chains.
• Integration of fan and twisted phase elements to induce self-rotation.
• Experimental demonstration of controllable focal points and rotating hollow regions.

Main Results:
