    Area of Science:

    • Optics and Photonics
    • Acousto-Optics
    • Optical Engineering

    Background:

    • Acousto-optic (AO) systems are crucial for beam steering and modulation.
    • Understanding AO scanning relationships is key to optimizing system performance.
    • Existing models may not fully capture the trade-offs in AO scanner design.

    Purpose of the Study:

    • To develop general scanning relationships for acousto-optic systems.
    • To analyze different scanning configurations and their limitations.
    • To identify optimal operating modes for maximizing scanner throughput rate.

    Main Methods:

    • Employed both geometric-optics and physical-optics approaches.
    • Utilized a diffraction analysis to categorize scanning configurations.
    • Investigated aperture-limited and repetition-rate-limited scenarios.

    Main Results:

    • Identified four basic scanning configurations: long/short chirp scanners.
    • Determined that short-chirp, repetition-rate-limited operation maximizes throughput.
    • Showcased that maximizing rate may compromise other performance parameters.

    Conclusions:

    • The developed scanning relationships provide valuable design insights for acousto-optic systems.
    • Optimal performance, specifically maximum throughput, is achieved with specific configurations.
    • Design choices involve trade-offs between throughput rate and other parameters.
