Automated fabric analyzer
The classical polarisation microscopy principles are used to determine c-axes orientations. Automatic control of polarizers, lamda-quater plate and viewing direction by a computer software, as well as automatic samples stage scanning enables fast acquisition of data (http://www.earthsci.unimelb.edu.au/facilities/analyser/).
