    A novel plastic microlens array enhances Shack-Hartmann wave-front sensor accuracy. This new sensor achieves superior measurement precision for wave-front characterization.

    Area of Science:

    • Optics and Photonics
    • Optical Metrology

    Background:

    • Shack-Hartmann wave-front sensing is crucial for optical system characterization.
    • Improving the accuracy and reproducibility of wave-front measurements is an ongoing challenge.

    Purpose of the Study:

    • To develop and evaluate a new plastic microlens array for Shack-Hartmann wave-front sensors.
    • To enhance the precision of wave-front measurement through improved sensor design.

    Main Methods:

    • Fabrication of a plastic microlens array with 900 individual 300 µm × 300µm lenslets and a 10 mm focal length.
    • Utilizing a deformable mirror to introduce controlled aberrations (defocus, astigmatism) for testing.
    • Measuring laser wave fronts using the developed Shack-Hartmann sensor and averaging frame memories to reduce spot centroiding error.
