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.
Claims18
A beam scanning device, comprising:
- a light modulation array 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;
- and
- a processor 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 determined to be located in the external space,
- wherein,
- the processor is further configured to, based on the light modulation array scanning the region of interest in the external space, control the light modulation array to perform the steering with a first degree of steering shift, and
- the processor is further configured to, based on the light modulation array scanning a region of non-interest that is a region in the external space other than the region of interest, control the light modulation array to perform the steering with a second degree of steering shift that is greater than the first degree of steering shift.
A beam scanning method, comprising:
- emitting a plurality of light beams to a light modulation array;
- and
- scanning an external space based on phase modulating the 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,
- wherein, in the scanning of the external space, the external space is scanned with a degree of steering shift varying depending on whether a region of interest is determined to be located in the external space, and
- wherein, in the scanning of the external space, a first degree of steering shift for the region of interest in the external space is less than a second degree of steering shift for a region of non-interest that is a region in the external space other than the region of interest.
