The impact of polarization‐maintaining and multimode fibre lengths on strain and temperature sensitivities of single‐mode–multimode–polarization‐maintaining–multimode–single‐mode‐based fibre optic sensors

open access: yesIET Optoelectronics, 2021
A fibre loop mirror sensor is proposed and demonstrated for strain and temperature measurements in experiment. In these schemes, fibre loop mirrors are constructed with single‐mode‐multimode‐polarization‐maintaining‐multimode‐single‐mode optical fibre ...

System design of gyro north-seeker calibration system

open access: yesThe Journal of Engineering, 2019
Aimed at the metrology support requirements of weapons found north orientation equipment, a gyro north-seeker calibration system is designed. The system uses one plane mirror and two 1 m collimators to set up three north benchmarks at the same time, and ...

Optical Characterization of a New Facility for Materials Testing under Concentrated Wavelength-Filtered Solar Radiation Fluxes

open access: yesSolar, 2023
The materials used to manufacture solar receivers for tower power plants must withstand high fluxes of concentrated solar radiation (from 0.1 to even 1.5 MWm−2) and operate at high operating temperatures (>800 °C).

Understanding what is visible in a mirror or through a window before and after updating the position of an object.

open access: yesFrontiers in Human Neuroscience, 2014
In the Venus effect observers assume that Venus is admiring her own reflection in the mirror (Bertamini et al. 2003). However, since the observer sees her face in the mirror, Venus is actually looking at the reflection of the painter.

Stationary entanglement between two movable mirrors in a classically driven Fabry-Perot cavity [PDF]

open access: yes, 2006
We consider a Fabry-Perot cavity made by two moving mirrors and driven by an intense classical laser field. We show that stationary entanglement between two vibrational modes of the mirrors, with effective mass of the order of micrograms, can be ...

A magnetic liquid deformable mirror for high stroke and low order axially symmetrical aberrations [PDF]

open access: yes, 2006
We present a new class of magnetically shaped deformable liquid mirrors made of a magnetic liquid (ferrofluid). Deformable liquid mirrors offer advantages with respect to deformable solid mirrors: large deformations, low costs and the possibility of very

High Power and Contamination Properties of All-Silica High Reflectivity Multilayers

open access: yesIEEE Photonics Journal, 2021
Optical multilayers created from a single material have been demonstrated to have lower stress and lower thermal expansion mismatch than standard two-material coatings; however, questions of high power operation and vulnerability to environmental ...

Mode-selective toroidal mirrors for unstable resonator planar waveguide and thin slab solid-state lasers [PDF]

open access: yes, 2009
In this paper, two new fabrication methods are developed for highly curved toroidal laser resonator mirrors based on laser micromachining of cylindrical substrates that already have the large lateral curvature RT provided by conventional polishing. These
