    Fourier telescopy offers high-resolution imaging of distant objects using phase closure to correct aberrations. This scalable, active-illumination technique achieves fine angular resolution, even with low-power illuminators.

    Area of Science:

    • Optics and photonics
    • Telescopic imaging
    • Wavefront sensing

    Background:

    • High-resolution imaging of distant objects is crucial for various scientific and industrial applications.
    • Existing techniques often face limitations in resolution, scalability, or power requirements.
    • Aberrations introduced by the intervening medium degrade image quality in long-distance imaging.

    Purpose of the Study:

    • To introduce and demonstrate Fourier telescopy, a novel technique for high-resolution imaging of distant objects.
    • To achieve scalable angular resolutions down to 1 nanoradian.
    • To enable imaging with low-power illuminators.

    Main Methods:

    • Fourier telescopy, a variant of Fourier microscopy, utilizes phase closure for aberration correction.
