Abstract
Acoustic optic deflectors (AOD) have gained a lot of popularity as a fast way to scan the laser beam in optical coherence systems. It produces an acoustic wave that deflects the laser beam in a single direction. There are many factors to consider when choosing different solutions for acousto-optic spectral systems, but no comprehensive analysis or summary of these factors exists. In addition to summarizing the most popular optical schemes for acousto-optic spectral systems, this paper explains the basic principles of acousto-optic devices. A simulation study has also been performed to represent the characteristics of AOD in a practical environment. Additionally, applications of acousto-optic spectral systems in a few common fields are presented.
