Abstract: In certain embodiments, a system may include a housing, one or more lenses, and a scanning system. The housing has an interior region. A lens is disposed within the interior region and transmits a light beam. The scanning system is disposed within the interior region and comprises a number of scanning cells, where each scanning cell comprises an electro-optical (EO) material. The scanning system performs the following for a number of iterations to yield a spot pattern: receive one or more voltages and electrically steer the light beam with the EO material from a current direction to a next direction in response to the voltages.
