The interaction of mechanical systems like membranes with the optical light field inside interferometers established access to manifold measurement schemes. The application of these measurement schemes spans the optical cooling of membranes, the investigation and manipulation of macroscopic quantum states, the detection and analysis of viruses and bacteria as well as the generation of non-classical states of light for quantum computing and gravitational wave detection. We present the analysis of thermal noise sources, which severely influence the performance of membrane-based interferometric measurement schemes. In particular, the influence of structural parameters such as geometry, temperature and loss mechanisms are studied to provide guidelines for future experimental set-ups.
