Abstract: A beam scanning device includes a light modulation array and a processor. The light modulation array is configured to scan an external space based on phase modulating a plurality of light beams and, in a state in which the plurality of light beams are arranged in a first direction, sequentially steering the plurality of light beams in a second direction different from the first direction. The processor is configured to control the light modulation array to cause a degree of steering shift of the light modulation array to vary depending on whether a region of interest is located in the external space.
