Abstract
This study looks at how to create perfectly rotating linearly polarized light using phase-shifting methods in a Sagnac interferometer, aiming to categorize optical devices. Theoretical analysis is conducted using Jones calculus, which provides a framework for understanding the propagation and phase shifting of linear light. Experimental results from the Sagnac interferometer show interference fringes that align with predictions from mathematical simulations. The experimental observations are validated through comparisons with Python-based simulations, ensuring the accuracy of the rotating polarized light characteristics. Additionally, Convolutional Neural Network (CNN) techniques are employed to analyze and verify the interference fringes, further confirming the consistency of the results with Jones calculus theory. This work demonstrates the potential for applying these methods in real-time, non-destructive optical measurements for the inspection and classification of materials such as polarizers and Half Wave Plates (HWPs), advancing the field of optical device characterization.
