Generation of articial thermal sources and their characterization by intensity interferometry

The Hanbury Brown and Twiss (HB-T) effect is fundamental to understand the nature of light, with important applications, for instance in ghost imaging. In this work, some coherence properties of the light emitted by an artifificial source were investigated. In particular, the second-order coherence...
