Summary
This study introduces a novel deep learning method to accurately identify elliptical beams (EBs) by precisely measuring their ellipticity factor. This breakthrough enhances EB applications in optical communication and beyond.
Area of Science:
- Optics and Photonics
- Artificial Intelligence
Background:
- Elliptical beams (EBs) are crucial structured light with unique properties.
- Practical applications of EBs are hindered by difficulties in determining physical quantities, especially the ellipticity factor.
Purpose of the Study:
- To develop a high-accuracy method for distinguishing elliptical beams (EBs) based on their ellipticity factor.
- To demonstrate the practical utility of this method in optical communication systems.
Main Methods:
- Utilized a transformer deep learning (DL) network for precise EB characterization.
- Achieved high accuracy in distinguishing EBs with minimal ellipticity factor differences (0.01).
Main Results:
- The DL model achieved 99% accuracy in classifying two distinct EB families.
- Demonstrated successful image transmission using EBs as information carriers with a low error bit rate of 0.22%.
Conclusions:
- The proposed DL approach offers a high-accuracy method for EB characterization, overcoming previous limitations.
- This advancement is poised to significantly expand the practical applications of EBs in fields like optical imaging, sensing, and quantum systems.
