Abstract
The present disclosure relates to optical devices and systems, specifically those related to light detection and ranging (LIDAR) systems. An example device includes a shaft defining a rotational axis. The shaft includes a first material having a first coefficient of thermal expansion. The device also includes a rotatable mirror disposed about the shaft. The rotatable mirror includes a multi-sided structure having an exterior surface and an interior surface. The multi-sided structure includes a second material having a second coefficient of thermal expansion. The second coefficient of thermal expansion is different from the first coefficient of thermal expansion. The multi-sided structure also includes a plurality of reflective surfaces disposed on the exterior surface of the multi-sided structure. The multi-sided structure yet further includes one or more support members coupled to the interior surface and the shaft.
