Polarization is a property of electromagnetic waves. Generally the light sources emit electromagnetic waves in the form of light not polarized, that is, the electric and magnetic fields vibrates in all directions randomly. There are substances that let through only part of the electromagnetic waves when they are traversed, this way it is possible to obtain polarized light, i.e., light propagates in only one plane. An example of polarizing material is Polaroid which is a type of plastic that offers resistance to the passage of light in one direction and less resistance in the other direction. The importance of polarization of electromagnetic waves in photonics is due to the dependence of the state of polarization that some equipment present and that the polarization of light can vary within the optical fiber, thus if the receiver is not aligned with the polarization that came only part of the power can be harnessed. There are other applications which also show the importance of polarization of light, some examples are that the chemical properties can be measured by analysing of the polarization that came through, another example is that when we use antennas it is possible to send up to two signal on the same frequency since the polarizations are orthogonal, among others. The objective of this project is to develop an FPGA-based digital hardware structure that is able to process data from analog to digital converters connected to the outputs of a conventional analog polarimeter, and calculate the Stokes parameters to later represent the state of polarization of light graphically on an LCD monitor in the Poincaré Sphere.
