Journal ArticleDOI
Exploitation of multiple incidences spectrometric measurements for thin film reverse engineering
TL;DR: The results show that multiple incidences, lead to the true solution for a filter with a large number of layers, even for a high number of variable parameters.
Journal ArticleDOI
Refractive index determination of SiO2 layer in the UV/Vis/NIR range: spectrophotometric reverse engineering on single and bi-layer designs
TL;DR: In this paper, the complex refractive index of SiO2 layer from 250 nm to 1250 nm was determined using spectrophotometric measurements and a clustering global optimization (CGO) procedure.
Journal ArticleDOI
Comparison of different dispersion models for single layer optical thin film index determination
TL;DR: In this paper, the optical properties of different single-layer thin films containing Ta 2 O 5, Si, Indium Tin Oxide and Au in the ultraviolet-visible and near infrared ranges were determined.
Journal ArticleDOI
Toward tunable thin-film filters for wavelength division multiplexing applications
TL;DR: A detailed analysis of the various problems connected with the development of tunable thin-film filters for wavelength-division multiplexing applications and describes and compares practical arrangements using either temperature or an electric field as the driving parameter.

Method and apparatus for determining color, in particular of a dental prosthesis
Michel Lequime,Jocelyn Millet +1 more
TL;DR: In this paper, an optical fiber instrument picks up light reflected from a tooth and transmits it to the inlet of a spectrocolorimeter which associated with a microprocessor in order to determine the diffuse spectral reflectance of the tooth and to calculate the tristimulus values of its apparent color under various different types of illumination.
