    Summary

    A novel wavelength-multiplexed optical scanning scheme deflects free-space beams using tunable lasers and wavelength-dispersive elements. This method achieves microsecond scan speeds with large apertures for precise angular deflection.

    Area of Science:

    • Optics and Photonics
    • Optical Engineering
    • Beam Steering Technologies

    Background:

    • Free-space optical beam steering is crucial for applications like optical communications and sensing.
    • Existing scanning methods often face limitations in speed, aperture size, or angular range.

    Purpose of the Study:

    • To propose and analyze a new wavelength-multiplexed optical scanning scheme.
    • To demonstrate microsecond domain scan setting speeds for optical beam deflection.
    • To explore the potential for large-aperture, sub-degree angular scans.

    Main Methods:

    • Utilizing a wavelength-multiplexed approach with tunable lasers or optical filters.
    • Employing a wavelength-dispersive optical element for beam deflection.
    • Analyzing scan range optimization based on diffraction order and grating period.

    Main Results:

    • The proposed scanner achieves microsecond scan setting speeds.
    • It supports large-diameter apertures (several centimeters or more).
    • Sub-degree angular scans are feasible with optimized parameters.

    Conclusions:

    • Wavelength-multiplexed optical scanning offers a promising method for high-speed, large-aperture beam deflection.
    • The technique is suitable for applications requiring rapid and precise angular control of optical beams.
    • Further research should address beam-spreading effects and information bandwidth limitations.
