Embodiments discussed herein refer to an integrated mirror motor galvanometer. The integrated mirror motor galvanometer repurposes a rotor of a motor to include at least one mirror face that redirects the light pulses interfacing therewith. This way, when the rotor oscillates along its range of rotation, the at least one mirror face also oscillates.
