…basic geometries commonly
referred to as Standard, Reverse, Look-Away, and Specular, as shown schematically in figure 2.
Advantages of the Standard geometry are speed and simplicity of calibration. The Reverse geometry is
often preferred for planar objects. The Specular geometry may…

…with reverse geometry, object height changes (Z axis) move the projected line in both the Z and Y axes of the object. This makes it more complex to interpret results. Because of this, reverse geometry is generally most useful with objects that have a relatively simple shape. The specular geometry

…electric field. This NPRO geometry also exhibits a clever trick: When
the crystal is placed in a magnetic field, it
acts as an optical isolator -- a unidirectional device whose forward transmission
is much higher than its transmission in
the reverse direction. Thus, the strongest…

…directed in an off-axis geometry through an oil immersion microscope objective so that the angle of incidence at the coverslip/sample interface is greater than the critical angle, as shown schematically in figure 1. In the prism based method, the orientation of the sample is reversed with respect to…

…1.
In the prism-based method, the orientation of the sample is reversed with respect
to the imaging objective. A light beam is
introduced to the sample through a prism
attached to the cover slip; the geometry
of the prism ensures that the incidence
angle at the sample…

The foils carrying the knife-edges and pinholes are photolithographically formed to define a precision geometry including positioning
reference marks. These position references are picked up when the
pinholes are laser-drilled in the foil, giving…
