Fresnel diffraction describes the complex light propagation that occurs when a wavefront encounters an abrupt phase change, typically at the boundary of two different media or at an engineered ...

How will technology impact your business over the next few years? Are you an early adopter or happily mainstream? Have your say in shaping the future of proptech within the property industry by taking ...

The research suggests that a relatively simple quantum set-up could be used to extract spatial information that is traditionally limited by the so-called Rayleigh criterion—a rule dating back ...

Once in a while, an artist who was successful in his time but forgotten soon after is “rediscovered” in a later era. Surprising examples of this are El Greco (1541–1614) and Johannes Vermeer ...

Tonight will be dry and plenty of clear spells will develop, with just a few areas of patchy cloud around. Sunday Tomorrow morning will stay dry with plenty of sunny spells. In the afternoon, it ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Erika Rasure is globally-recognized as a ...

Abstract: An electrically tunable optical zooming holographic projection system with a fixed location of zeroth-order diffraction is demonstrated. By using two liquid lenses and an encoded Fresnel ...

Abstract: Starting from Fresnel diffraction theory, we derive analytic expressions for the lateral spatial dependence of feedback fields for the cases of conventional and phase-conjugate optical ...

The DIALS project is a collaborative endeavour to develop new diffraction integration software to meet the data analysis requirements presented by these recent advances. There are three end goals: to ...

In this case, the light intensity distribution in the measurement volume is built numerically by solving the Fresnel diffraction formula for holographic near-field diffraction [6]. However, CCD ...

We circumvent the diffraction limit of the optics by mapping the lateral ... and find a two-point resolution of 275 nm using 800 nm light that satisfies the Rayleigh criterion. We also derive a ...
