This paper introduces a single-shot lensless imaging method using a Fresnel zone aperture and incoherent illumination. The technique eliminates the need for multiple masks or shots, reconstructing images with significantly improved signal-to-noise ratio by using compressive sensing to mitigate twin-image artifacts common in conventional lensless methods.

This paper presents a novel approach to lensless imaging with a single-shot capture, which is a significant advantage over multi-shot methods. The use of a Fresnel zone aperture and compressive sensing effectively eliminates twin-image artifacts and suppresses noise, leading to high-quality reconstructions. The proposed method has potential for various applications, including portable cameras and integrated imaging systems. While there are limitations regarding resolution and potential model errors due to diffraction, the innovative approach and demonstrated results warrant a strong rating.
