    Area of Science:

    • Optics and Imaging Technology
    • Computer Vision

    Background:

    • Conventional stereoscopic imaging often involves complex setups.
    • Limitations exist in current 2D systems for depth perception.
    • Advancements in optical deflectors can enable novel imaging solutions.

    Purpose of the Study:

    • To develop a compact, single-channel stereoscopic video imaging modality.
    • To evaluate the performance and depth perception capabilities of the new system.
    • To assess the potential for integration with existing 2D imaging platforms.

    Main Methods:

    • A transparent rotating deflector (TRD) was employed to capture sequential left and right 2D images.
    • A microcontroller unit synchronized camera operations and TRD rotation.
    • Image quality was assessed using the structural similarity index (SSIM).
    • Depth perception was evaluated through quantitative estimation and subjective analysis.

    Main Results:

    • The developed modality successfully generated stereoscopic video images.
    • TRD rotation and stepping motor heat generation were characterized.
    • Image quality and stability were maintained, as indicated by SSIM.
    • Subjective analysis confirmed improved depth perception.

    Conclusions:

    • The single-channel stereoscopic video imaging modality overcomes limitations of conventional systems.
    • It presents a potential economical and compact solution for stereoscopic imaging.
    • The system can be integrated into existing 2D optical modalities.
    • Applications span medical and industrial fields requiring depth perception.
