A LIDAR system including a MEMS scanning device is disclosed. The LIDAR system includes a light source, a light deflector, a sensor, and a processor. The light deflector deflects light from the light source or light received from an environment outside a vehicle in which the LIDAR system is installed. The sensor detects the light received from the light source or the environment. The processor determines a distance of one or more objects in the environment from the vehicle based on the signals from the sensor. The light deflector includes one or more actuators, which include one or more actuating arms. Connectors connect the actuating arms to an MEMS mirror or other deflector. The actuating arms move when subjected to an electrical field in the form of a voltage or current. Movement of the actuating arms causes movement of the MEMS mirror or deflector causing it to deflect light.
