Setup of a Michelson Interferometer (MI), using amplitude splitting, and analysis of the generated interferograms in several configurations.
Usage of cube beam splitters and polarisation optics to control laser beam polarization.
Assessment of how the MI can be used to measure relative displacements of one of the mirrors, using a piezo electric stage actuator to move one of the mirrors.
Analysis of several polarization optical elements (polarizers, polarizing beam splitters and wave plates) using a polarimeter (an instruments that measure the polarisation state of light).
Assembly of a homodyne quadrature detection configuration to achieve higher resolution compared to the previous simple homodyne detection.
Acquisition of interferograms using a CMOS 2D camera for psot processing.
