Polarization Adds a New Perspective to the Imaging Industry

Lucid Vision Labs. In many machine vision applications, the use of polarization cameras can provide information that cannot be obtained with standard monochrome, color, multi-spectral or hyperspectral cameras. Applications that benefit from the use of polarization cameras are those in which reflected and transmitted scenes must be separated, the shape of transparent objects must be analyzed, and where removing specularities and haze is important. To appreciate how such applications can benefit from the use of polarization, the nature of light and how it interacts with such materials must be understood. Light is an electromagnetic wave that is composed of an electric field and a perpendicular magnetic field.
