Holography (class 1 of 3)
28 Fevereiro 2024, 15:00 • Alexandre Pereira Cabral
Setup of a Denisyuk configuration, consisting of a volume-reflection holography technique. As a recording medium, a silver halide emulsion on a glass plate will be used (a matrix of cohesive silver crystals in a transparent medium). During exposure, the reference wave and the waves reflected from the object result in an interference structure that was recorded within the emulsion.
Students produced their own objects that will be exposed in a 50 mm x 50 mm plate.
Students performed several exposures using different types of objects (including lenses or mirrors to generate holographic optical elements known as HOE.
Analysis of non-holographic technics, bases on the Peper’s ghost concept, will be shown in the lab for analysis.EM properties of matter
