    We developed a Hartmann sensor capable of detecting extremely small wavefront changes with high precision. This advanced optical sensor achieved a sensitivity of lambda/15,500, enabling precise wavefront measurements.

    Area of Science:

    • Optical Metrology
    • Wavefront Sensing
    • Interferometry

    Background:

    • Accurate wavefront measurement is crucial for optical system performance.
    • Existing sensors may lack the sensitivity required for detecting subtle wavefront aberrations.

    Purpose of the Study:

    • To introduce a novel Hartmann sensor with enhanced sensitivity.
    • To demonstrate the sensor's capability in measuring minute wavefront variations.

    Main Methods:

    • Utilized a Hartmann sensor operating at a wavelength of 820nm.
    • Employed the sensor to measure an ultra-small change in wavefront.
    • Validated the measurement against theoretical expectations.

    Main Results:

    • Achieved a sensor sensitivity of lambda/15,500 at 820nm.
