Compound dichroic polarizers using liquid crystal polymers and dichroic dyes have been studied for their variation of polarization with wavelength. Compound dichroic polarizers are composed of multilayer polarizers, where each layer has a different orientation and absorption spectrum. Several wavelength-dependent transmission axes configurations are proposed and investigated. Polarization properties, such as linear and circular diattenuation of the compound dichroic polarizers, for different wavelengths are measured and compared with simulation. Depending on the configuration, the compound dichroic polarizers can convert polarization signatures into color coding in unique ways.
