Disclination lines are one-dimensional topological defects in the orientational order of nematic liquid crystals and represent an important topic in modern soft matter physics. They are of significant interest due to their interactions with colloids and light, while also serving as model systems for studying topological defects across other branches of physics. In this master's thesis, I focused on the development of an experimental system where elastic energy is injected into a liquid crystal cell via the rotation of its surfaces, resulting in the deformation of a disclination line between two surface defects. I demonstrated the utility of this system through an experiment featuring a basic Frank-Read source consisting of two point defects with topological charges +1/2 and -1/2, followed by an upgraded version with +1 and -1 topological charges. Finally, I performed an experiment demonstrating the generation of arbitrary disclination line deformations through controlled cell rotation.
