PI-300 WPI-200
Even when brightness differences are too subtle for the naked eye to detect, polarized light images can reveal minute irregularities.

Polarized Light Image
Makes it easier to identify surface irregularities.
Using reflected light, the fiber orientation of materials like CFRP (carbon fiber reinforced polymer) can be visually evaluated as the direction of the polarizing principal axis.

Evaluation of New Fiber Materials
Traditional polarization cameras (e.g., PI) cannot obtain complete polarization data.
WPI measures the Degree of Polarization (DOP) and distinguishes between clockwise and counterclockwise circularly polarized light.
WPI is a revolutionary camera that acquires Stokes parameters indicating the polarization state.
