Abstract: Rotatable mirror assemblies and light detection and ranging systems containing rotatable mirror assemblies are described herein. An example rotatable mirror assembly may include (1) a housing having a top end, a bottom end, and a longitudinal axis intersecting the top and bottom ends, and (2) a set of reflective surfaces, where each reflective surface in the set is coupled to the top end of the housing and the bottom end of the housing such that each reflective surface possesses limited freedom of movement with respect to the housing.
