Beam steering apparatus, method of driving the beam steering apparatus, and spatial information acquisition apparatus using the beam steering apparatus
A beam steering apparatus, a method of driving the beam steering apparatus, and a spatial information acquisition apparatus using the beam steering apparatus, are provided. The beam steering apparatus includes a light source, and a steering array including elements having refractive indexes varying with a voltage driving the steering array, the elements being configured to control a direction of a beam from the light source and incident on the steering array. The beam steering apparatus further includes a driver configured to generate the voltage, based on an intermediate value of at least two voltages, and drive the steering array, based on the generated voltage.
