    Area of Science:

    • Optical metrology
    • Interferometry
    • Surface characterization

    Background:

    • Accurate measurement of optical surfaces is crucial for high-performance optical systems.
    • Traditional methods can be limited in precision or applicability.
    • Spatial filtering offers potential for enhanced measurement accuracy.

    Purpose of the Study:

    • To investigate the efficacy of a phase stripe as a spatial filter for optical surface measurement.
    • To adapt Zernike's phase contrast method for zonal measurement using the caustic method.
    • To evaluate different phase stripe path differences for optimal performance.

    Main Methods:

    • Utilized the caustic method for optical surface measurement.
    • Implemented a phase stripe as a spatial filter, adapting Zernike's phase contrast principles.
    • Analyzed path differences of lambda/4, lambda/3, and lambda/2 for the phase stripe.
    • Tested a mirror using the optimal phase stripe configuration.

    Main Results:

    • Evaluated phase stripe path differences of lambda/4, lambda/3, and lambda/2.
    • Identified lambda/3 as the optimal path difference for the phase stripe.
    • Achieved a mean square deviation of 0.0076 lambda in mirror measurements with the lambda/3 stripe.

    Conclusions:

    • A phase stripe functions effectively as a spatial filter in caustic-based optical surface measurements.
    • The lambda/3 path difference provides the best results for this technique.
    • This adapted phase contrast method offers high precision for zonal surface analysis.
