Motivated with predictions theorised by T. Cheng and M. Spinrath, we have tested the described detection method for dark matter using a modified Michelson interferometer. In the first section a explanation of the modified Michelson interferometer was given. The modification is a replacement of a mirror with a silicon nitrade membrane. Parts of the experiments, such as beamsplitter, polarizing beamsplitter, and the homodyne detection method with it’s advangeges of low noise were discussed. The fast Fourier transform algorithm was used as one of the fundamental computational tools in data analysis, as well as a breif explanation of the Cooley-Tukey algorithm. In the second section an explanation of the experimental setup was given, as well as the optical path from the laser source to the detector. Physical characteristics of the membrane were given, a description of photodetector and acusto-optical modulator was also given. In the third section I describe methods of data collection, analysis using the HPC Bura, and storage for further analysis. In the end I present the calibration factor determined by use of the procedure given and developed by M. Vretenar, results of the data folding method, an attempt to find anomalous signals, and lastly those anomalous signals were normalized by their amplitudes and number of hits per amplitude to get their probabilites.
