Tilted Wave Fizeau Interferometer for flexible and robust asphere and freeform testing

open access: yesLight: Advanced Manufacturing, 2022
Tilted Wave Interferometry (TWI) is a measurement technique for fast and flexible interferometric testing of aspheres and freeform surfaces. The first version of the tilted wave principle was implemented in a Twyman-Green type setup with separate ...

Uncertainty Model for Total Solar Irradiance Estimation on Australian Rooftops

open access: yesE3S Web of Conferences, 2017
The installations of solar panels on Australian rooftops have been in rise for the last few years, especially in the urban areas. This motivates academic researchers, distribution network operators and engineers to accurately address the level of ...

Surface profile prediction and analysis applied to turning process [PDF]

open access: yes, 2008
An approach for the prediction of surface profile in turning process using Radial Basis Function (RBF) neural networks is presented. The input parameters of the RBF networks are cutting speed, depth of cut and feed rate.

Temperature and strain discrimination using a single tilted fibre Bragg grating [PDF]

open access: yes, 2007
A fibre optic sensor capable of discriminating between temperature and strain, using a single fibre Bragg grating, is presented. The technique exploits the core–cladding mode coupling of a tilted fibre Bragg grating (TFBG). The core and cladding modes

Optimization of plasmon–plasmon coupling in photorefractive layered media [PDF]

open access: yes, 2013
In this paper we study grating-induced plasmon–plasmon coupling in photorefractive layered media using a weakcoupling approximation. The method used is applicable to general layered structures that support both plasmonic and optical modes, such as ...

Electron diffraction of tilted perovskites [PDF]

open access: yes, 2005
Simulations of electron diffraction patterns for each of the known perovskite tilt systems have been performed. The conditions for the appearance of superlattice reflections arising from rotations of the octahedra are modified to take into account ...
