    Area of Science:

    • Optics and Photonics
    • Wavefront Sensing and Metrology

    Background:

    • Accurate measurement of optical wavefronts is crucial for applications like adaptive optics and optical testing.
    • Existing wavefront sensors, such as the Shack-Hartmann sensor, have limitations in resolution and dynamic range.

    Purpose of the Study:

    • To introduce a new type of wavefront sensor utilizing a programmable moving aperture.
    • To demonstrate its potential for achieving higher resolution wavefront reconstruction compared to existing technologies.

    Main Methods:

    • A programmable aperture scans the incoming wavefront.
    • The position of a diffraction spot is recorded by a 2D sensor behind an objective lens.
    • Wavefront is reconstructed by processing the localized slope data obtained from the aperture's position.

    Main Results:

    • The sensor provides an estimate of the local wavefront slope at the aperture's position.
    • The device, a programmable Hartmann wavefront sensor, achieves higher resolution due to a longer focal length.
    • A practical implementation using a liquid-crystal television as the programmable aperture is successfully demonstrated.

    Conclusions:

    • The proposed programmable aperture wavefront sensor offers a viable alternative for high-resolution wavefront measurement.
    • While sacrificing real-time operation, the increased resolution makes it suitable for specific metrology applications.
    • The use of a liquid-crystal television demonstrates the feasibility of practical implementation.
