SNAPSHOT ELLIPSOMETER

A snapshot ellipsometer or polarimeter which does not require temporally modulated element(s) to measure a sample, but instead uses one or more spatially varying compensators, (eg. microretarder arrays and compound prisms), to vary the polarization state within a measurement beam of electromagnetic...

Beschreibung
Zusammenfassung:	A snapshot ellipsometer or polarimeter which does not require temporally modulated element(s) to measure a sample, but instead uses one or more spatially varying compensators, (eg. microretarder arrays and compound prisms), to vary the polarization state within a measurement beam of electromagnetic radiation. Analysis of the intensity profile of the beam after interaction with the spatially varying compensator(s) and the sample allows sample parameters to be characterized without any moving optics.
