Title: High numerical aperture Mueller matrix polarimetry and applications to multiplexed optical data storage
Authors: Macias Romero, Carlos Alberto
Item Type: Thesis or dissertation
Abstract: Optical data storage has reached a point where it is no longer possible to increase the storage capacity of an optical disk by conventional means. The work presented here, however, proves experimentally the validity of a novel solution to increase the capacity of an optical disk. Polarisation is used to store information multiplexed into shape-birefringent pits. A high numerical aperture scanning confocal microscope capable of measuring the Muller matrix of a sample is built to measure and characterise the polarisation properties of such pits. A number of results found during the development of the apparatus are given. Novel contributions are shown in the areas of imaging, the theory of coherence and polarisation, polarisation imaging, linear algebra, polarisation confocal microscopy, and optical data storage. It is shown that the storage capacity of any existent non-volumetric optical technology can be increased by 7.16 times, at least.
