Figure 9
Sample images of (a) $[ |{\rm sin}\, \delta |]$ , (b) orientation angle $[\phi]$ and (c) light transmission I₀ for a region of an anhydrite rock section with a thickness of 0.03 mm. The images correspond to the external tilt angles $[\Theta _{1}]$ and $[\Theta _{2}]$ of the tilting stage set equal to zero.
