On the diffraction limit for lensless imaging
Journal of Research of the National Institute of Standards and Technology, 1999 The diffraction limit for lensless imaging, defined as the sharpest possible point image obtainable with a pinhole aperture, is analyzed and compared to the corresponding limit for imaging with lenses by means of theoretical considerations and numerical computations using the Fresnel-Lommel diffraction theory for circular apertures.

Investigating the performance of regular two-dimensional grating in a lensless system
HeliyonIn this study, we investigate the use of a regular two-dimensional (2D) grating as an encoded mask in a lensless imaging system, a novel approach in the field of computational imaging.

Sensing Approaches and Reconstruction Methods for Improved Lensless Imaging [PDF]
, 2023 Lensless imaging system is a novel alternative to traditional camera design where the lensof the camera is replaced with another optical encoder(coded mask) that is thin, flat, and potentially inexpensive.

High-resolution self-referencing incoherent single-shot lensless imaging with direct image retrieval
Lensless imaging is a family of techniques that can produce images without the need for imaging optics. Conventional lensless imaging usually requires some combination of coherent illumination, a reference beam, an optical encoder, and an iterative image

Ultrastable XUV interferometry for broadband lensless imaging
, 2014 Lensless imaging is the technique of numerically reconstructing an image of a sample instead of imaging the sample on the camera using lenses. This is an interesting solution for microscopy with extreme ultraviolet (XUV) and X-ray radiation, as good ...
