Centre Symmetry Sets of Families of Plane Curves
Demonstratio Mathematica, 2015 We study centre symmetry sets and equidistants for a I-parameter family of plane curves where, for a special member of the family, there exist two inflexions with parallel tangents.

Reconstructing the Spatial Parameters of a Laser Beam Using the Transport-of-Intensity Equation
Sensors, 2022 A simple method for reconstructing the spatial parameters of a laser beam, based on the transport-of-intensity equation, is presented. Registration of cross-section intensity distributions in several planes was carried out using a single CMOS camera. The

Three-dimensional spatiotemporal focusing of holographic patterns
Nature Communications, 2016 Three-dimensional computer-generated holography cannot be implemented with temporal focusing. Here, Hernandez et al. use two spatial light modulators to control transverse- and axial-target light distribution, generating spatiotemporally focused patterns

Computational Method for Wavefront Sensing Based on Transport-of-Intensity Equation
Photonics, 2021 Recently the transport-of-intensity equation as a phase imaging method turned out as an effective microscopy method that does not require the use of high-resolution optical systems and a priori information about the object.

The wavefront of the radio signal emitted by cosmic ray air showers [PDF]
, 2014 Analyzing measurements of the LOPES antenna array together with corresponding CoREAS simulations for more than 300 measured events with energy above $10^{17}\,$eV and zenith angles smaller than $45^\circ$, we find that the radio wavefront of cosmic-ray ...

Optical Aberrations and Wavefront
Türk Oftalmoloji Dergisi, 2014 The deviation of light to create normal retinal image in the optical system is called aberration. Aberrations are divided two subgroup: low-order aberrations (defocus: spherical and cylindrical refractive errors) and high-order aberrations (coma ...

Telescope to Observe Planetary Systems (TOPS): a high throughput 1.2-m visible telescope with a small inner working angle [PDF]
, 2006 The Telescope to Observe Planetary Systems (TOPS) is a proposed space mission to image in the visible (0.4-0.9 micron) planetary systems of nearby stars simultaneously in 16 spectral bands (resolution R~20). For the ~10 most favorable stars, it will have

Numerical treatment of the light propagation problem in the post-Newtonian formalism [PDF]
, 2009 The geometry of a light wavefront, evolving from a initial flat wavefront in the 3-space associated with a post-Newtonian relativistic spacetime, is studied numerically by means of the ray tracing method.
