High-precision measurements implemented with light are desired in all fields of science. However, light acts as a wave, and the Rayleigh criterion in classical optics yields a diffraction limit that prevents obtaining a resolution smaller than the wavelength. Sub-wavelength interference has potential application in lithography because it beats the classical Rayleigh resolution limit. Here, we carefully study second-order correlation theory to establish the physics behind sub-wavelength…

Super sub-wavelength interference via high-order correlation of light fields
We propose a scheme to realize super sub-wavelength interference in virtue of high-order spatial correlation with a programmable light source, which can be applied to enhance precision in measurement
Direct measurement of sub-wavelength interference using thermal light and photon-number-resolved detection
We examine thermal light diffracted through a double slit using photon-number-resolved detection to directly measure high-order spatial correlations, and we see sinusoidal modulations of those
High-resolution interference with programmable classical incoherent light.
Compared with other schemes for observing interference patterns, only single-pixel detection is needed in this proposal and the high-resolution interference pattern can be inverted to obtain an image with better resolution compared with that of the scheme proposed by Erkmen.
Fourier-Transform Ghost Imaging with Hard X Rays.
A novel lensless Fourier-transform ghost imaging method with pseudothermal hard x rays that extends x-ray crystallography to noncrystalline samples and provides a potential solution for lensless diffraction imaging with fermions, such as neutrons and electrons where intensive coherent sources usually are not available.
Measuring mode indices of a partially coherent vortex beam with Hanbury Brown and Twiss type experiment
It is known that the cross-correlation function (CCF) of a partially coherent vortex (PCV) beam shows a robust link with the radial and azimuthal mode indices. However, the previous proposals are
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.
Enhancement of spatial resolution of ghost imaging via localizing and thresholding
In ghost imaging scheme, an illuminated light is split into test and reference beams which pass through two different optical systems respectively and an image is constructed by the second-order

Experimental results of controllable two-photon interference fringes with thermal light in an incoherent rotational shearing interferometer with orthogonally polarized beams are reported on.
Spatial sub-Rayleigh imaging analysis via speckle laser illumination.
By confining the divergence of the optical field, as well as the size of the illumination source, it is shown that the first-order averaged intensity measurement via speckle laser illumination can make an actual breakthrough on the Rayleigh limit.


Correlation between Photons in two Coherent Beams of Light
Physicists now rely on the effect to probe the quantum character of complex light sources as well as classical interferometry to infer the angular size of distant stars.
Incoherent coincidence imaging and its applicability in X-ray diffraction.
A proposal to realize lensless Fourier-transform imaging is given, and its applicability in x-ray diffraction is discussed, and a particular aspect of coincidence imaging with incoherent sources is studied.
Quantum interferometric optical lithography: exploiting entanglement to beat the diffraction limit
It is shown how to write arbitrary 2D patterns by using the nonclassical photon-number states method, and a factor of N = 2 can be achieved easily with entangled photon pairs generated from optical parametric down-conversion.

I propose a quantum imaging method that can beat the Rayleigh-Abbe diffraction limit and achieve de Broglie resolution without requiring a multiphoton absorber or coincidence detection. Using the
Engineering of two-photon spatial quantum correlations behind a double slit
This paper demonstrates the engineering of spatially entangled two-photon states behind a double slit by tailoring the incident pure two-photon state. We experimentally characterize many different
On the efficiency of quantum lithography
Quantum lithography promises, in principle, unlimited feature resolution, independent of wavelength. However, in the literature, at least two different theoretical descriptions of quantum lithography
Relationship between resolution enhancement and multiphoton absorption rate in quantum lithography
The proposal of quantum lithography [Boto et al., Phys. Rev. Lett. 85, 2733 (2000)] is studied via a rigorous formalism. It is shown that, contrary to Boto et al.'s heuristic claim, the multiphoton
We report an interference experiment in which photon pairs generated by spontaneous parametric down-conversion produce a Young-type fourth-order interference pattern after being scattered by two
Introduction to the special issue on quantum imaging
A major research initiative was proposed in 2003 at the Army Research Office to create a so-called MURI—a Center (delocalized, but nevertheless logistically a Center)—to explore further this emerging field of Quantum Imaging.
About photon correlations
Some general properties of photon correlations are discussed in a simple way through an analysis of the two-detector measurement scheme. It is shown that the assumption of the discreteness of the
