Journal ArticleDOI
Interferometric Measurement of Refractive Index Variations in Infra-red Transmitting Materials at 10·6 μm
Richard E. Gaskin,Colin Lewis +1 more
TL;DR: In this paper, a procedure for determining the gross refractive index variations in infra-red transmitting materials was developed for determination of the Gross Refractive Index (GVI) using an infra red interferometer operating at 10·6 μm, with a pyroelectric vidicon.
Chalcogenide glasses for infrared applications: New synthesis routes and rare earth doping
TL;DR: In this paper, the synthesis of chalcogenide glass and glass-ceramics using Spark Plasma Sintering (SPS) has been investigated for the purpose of thermal imaging.
Journal ArticleDOI
An Afocal-system OTF Test Standard
TL;DR: The design and construction of a special afocal system in the form of a straight-through telescope is described and the calculated and experimentally measured values for the MTF of the system are compared.
Journal ArticleDOI
The effect on optical performance of grain boundaries in germanium
TL;DR: In this paper, the modulation transfer function obtained via inverse transformation of the line spread function, and autocorrelation of the pupil function obtained by interferometry are discussed together with results from recent work using computer modelling.
