Polarization imaging camera
PI-110

Polarization can be observed easily in real time in such a way as to use a normal camera.
Brightness, polarization intensity and polarization direction are output by the accompanying software, so a quantitative analysis is done easily.
PI-110 can show another information that we couldn't ever see.

Angle of polarizer [degrees]
An array of polarizers with four different transmission axes is combined with an image sensor.
By comparing signals of the four pixels, it is possible to calculate polarization azimuths and degree of linear polarization.

Shape recognition by polarization direction

Image of polarization direction
degrees
Polarization direction of reflected light from objects varies depending on the direction of the surface of the objects.For this reason, fine surface irregularities can be observed by the polarization images.

Visualization and quantification of fiber orientation direction of carbon fiber reinforced plastic(CFRP)

【 Numerical extraction of fiber orientation direction 】
It can be seen that the fiber orientation angles of the two regions are different by about 95 degrees.
Fiber direction
The direction of polarization indicated by color
The fiber orientation direction of CFRP can be clearly distinguished by polarized image. Various numericalization is also possible by data processing.
