POLARIMETRY

Polarimetry is the measurement and interpretation of the geometrical orientation of the electromagnetic wave oscillations.

The last years we have been working on a research line related to the design, optimization and implementation of polarimeters, the main devices to perform polarimetric metrology. The main study is focused on the design of polarimeters based on birefringent materials, including liquid crystal and biaxial-crystals (the latter group based on the conical refraction phenomenon). Recently, the implemented polarimeters are being used for different applications, from the characterization of the optical properties of materials to the contrast enhancement of images. 

 

The polarization measurement of light and the materials response is performed by Stokes and Mueller polarimeters(using the Mueller formalism). One part of our study is focused on the design and optimization of polarimeters based on birefringent materials, including liquid crystal and biaxial-crystals (the latter group based on the conical refraction phenomenon).

The implemented polarimeters are being used for different applications, from the characterization of the optical properties of materials (e.g. the refraction index) to the contrast enhancement of images (e.g. biological tissues images). The contrast enhancement of images are based on different decompositions of the Mueller matrix information. We study which decomposition give more acurate physical information.
