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.
