PI/WPI Series features
Observation of surface bumps,
made clear by polarization effects
Polarization allows detecting small edges and surface irregularities that would be difficult to see using normal cameras. Polarization imaging especially shines when observing dark objects.
Left: normal image ; Right: polarization image ; Surface bumps are distinctly seen on polarization images.
PI/WPI Series features
Evaluation of new materials
(carbon fiber …)
Using reflected light, polarization can be used to observe and quantify in real-time the orientation of the fibers in a CFRP (Carbon Fiber Reinforced Polymer) sample.

PI/WPI Series features
Full-Polarization imaging
with WPI
Polarization cameras on the market, including PI, provide only limited polarization information, not the whole picture.
In contrast to such cameras, WPI systems have access to the full-fledged Stokes parameters, allowing discernment among right-handed, left-handed, elliptical and circular polarization states. Furthermore, WPI systems differentiate between polarized and unpolarized light, and do not mix up elliptical polarizations with unpolarized light. The WPI system is the optimal choice for full polarization measurement.
