Frequency conversion of structured light [PDF]

open access: yesScientific Reports, 2015
We demonstrate the coherent frequency conversion of structured light, optical beams in which the phase varies in each point of the transverse plane, from the near infrared (803nm) to the visible (527nm).

Diffuse structured light [PDF]

open access: yes2012 IEEE International Conference on Computational Photography (ICCP), 2012
Today, structured light systems are widely used in applications such as robotic assembly, visual inspection, surgery, entertainment, games and digitization of cultural heritage. Current structured light methods are faced with two serious limitations.

Structured light scatteroscopy [PDF]

open access: yesJournal of Biomedical Optics, 2014
A new imaging approach, structured light scatteroscopy (SLS), is demonstrated, which offers rapid wide-field imaging of microscopic morphological variations in bulk tissue surfaces. Elastic scattering of light offers exquisite sensitivity to ultrastructural changes at multiple size scales ranging from nanometers to millimeters, but in bulk tissues the ...

Kaleidoscopic structured light [PDF]

open access: yesACM Transactions on Graphics, 2021
Full surround 3D imaging for shape acquisition is essential for generating digital replicas of real-world objects. Surrounding an object we seek to scan with a kaleidoscope, that is, a configuration of multiple planar mirrors, produces an image of the object that encodes information from a combinatorially large number of virtual viewpoints.

Concealing with Structured Light [PDF]

open access: yesScientific Reports, 2014
While making objects less visible (or invisible) to a human eye or a radar has captured people's imagination for centuries, current attempts towards realization of this long-awaited functionality range from various stealth technologies to recently proposed cloaking devices. A majority of proposed approaches share a number of common deficiencies such as

Multiprojector Multicamera Structured Light Surface Scanner

open access: yesIEEE Access, 2022
Structured light surface scanners are usually limited to a single projector and cannot provide a full surface profile in a single scan. Multiple projectors must be employed to extend the imaging area over the whole surface of the imaged object.

Structured Light Profilometry on m-PTC

open access: yesEnergies, 2020
In concentrating solar systems, it is essential to study the optical losses of the collectors. A fundamental parameter is the intercept factor, namely, the fraction of sunrays reflected by the concentrator that reaches the receiver.

Structured Optical Materials Controlled by Light [PDF]

open access: yes, 2018
Materials of which the optical response is determined by their structure are of much interest both for their fundamental properties and applications. Examples range from simple gratings to photonic crystals.
