    Area of Science:

    • Optics and Photonics
    • Metrology
    • Computational Imaging

    Background:

    • Traditional 3D sensing methods face limitations in accuracy and multi-point measurement.
    • Diffractive Optical Elements (DOEs) offer unique light manipulation capabilities.
    • Improving depth resolution in camera-based systems is crucial for various applications.

    Purpose of the Study:

    • To develop and validate a camera-based sensor for high-accuracy, multi-point 3D distance measurement.
    • To investigate the use of a DOE with a vortex point spread function (PSF) for enhanced depth sensing.
    • To demonstrate the benefits of a replication (multipoint) approach for improving measurement accuracy.

    Main Methods:

    • Integration of a DOE with a spiral phase mask into a camera lens.
    • Utilizing the defocus-sensitive rotation of the vortex PSF for depth reconstruction.
    • Implementing a multipoint method by averaging depth measurements from replicated spots.

    Main Results:

    • Achieved an accuracy of 8.51 µm over a 20 mm depth range.
    • Demonstrated a measurement volume of 70 mm × 50 mm × 20 mm.
    • Showcased accuracy improvement by a factor of up to 3 using the replication approach.

    Conclusions:

    • The proposed camera-based sensor with DOE achieves high-accuracy 3D position sensing for multiple points.
    • The multipoint method significantly enhances both depth and lateral measurement precision.
    • This technology enables advanced single-camera 3D sensing with high resolution.
