Numerical Study of an Acousto-Optic Interaction

Abstract

This thesis is a study focused on the acousto-optic interaction, which involves the interaction between sound and light waves in a specific medium called an acousto-optic material. This work begins with a theoretical study of this phenomenon and focuses on the relationship between the position of diffracted orders and the modulating signal. To ensure the accuracy of the numerical model, a series of experiments are conducted. The thesis is structured into three chapters; the first chapter covers physical principles, including different types of diffraction, most importantly the grating diffraction. The second chapter provides an overview of the physical principles underlying acousto-optic interaction, while the third chapter discusses a MATLAB simulation that analyzes the effects of various parameters on the interaction, leading to a deeper understanding of the phenomenon's behavior.
