It is commonly accepted that optical sub-Rayleigh imaging has potential application in many fields. In this Letter, by confining the divergence of the optical field, as well as the size of the illumination source, we show that the first-order averaged intensity measurement via speckle laser illumination can make an actual breakthrough on the Rayleigh limit. For a high-order algorithm, it has been reported that the autocorrelation function can be utilized to achieve the sub-Rayleigh feature…

Sub-Rayleigh resolution single-pixel imaging using Gaussian- and doughnut-spot illumination.
Gaussian- and doughnut-shaped spots are used to alternatively illuminate an object and a single-pixel detector located after the object is employed to collect the transmitted light as two bucket signals, respectively to achieve a sub-Rayleigh resolution image.
Resolution enhancement of ghost imaging in atom vapor.
It is demonstrated experimentally that the speckle size can be compressed by a coherent population trapping (CPT) process in atom vapor, and the resolution of GI can be greatly enhanced by the CPT process.

Second order intensity correlations of speckle illumination are extensively used in imaging applications that require going beyond the Rayleigh limit. The theoretical analysis shows that
Spatially modulated thermal light in atomic medium for enhanced ghost imaging
The spatially modulated thermal light was used to enhance the image resolution in ghost imaging of which the resolution was enhanced by factor 3, since the ghost image resolution is heavily reliant on the speckle’s transverse coherent length.


Sub-Rayleigh imaging via speckle illumination.
Imaging beyond the conventional Rayleigh limit is achieved by illuminating the object with pseudothermal light that exhibits a random speckle pattern and the resolution of the image is shown to be related to the size of the speckled pattern that is tied to the lateral coherence length of the pseudothermalLight.
Super-resolution and reconstruction of sparse sub-wavelength images.
We show that, in contrast to popular belief, sub-wavelength information can be recovered from the far-field of an optical image, thereby overcoming the loss of information embedded in decaying

A chip-scale, electrically pumped semiconductor laser based on a novel design is presented, demonstrating high power per mode with much lower spatial coherence than conventional laser sources, which could enable a wide range of full-field imaging applications.
Resolution analysis in computational imaging with patterned illumination and bucket detection.
This Letter shows that the resolution of the recovered image is only limited by the numerical aperture of the projecting optics regardless of the quality of the collection optics, and provides experimental verification of image retrieval even when an optical diffuser prevents imaging with a megapixel array camera.
