Abstract
An object detector is provided including a light emitter including at least a light source having a plurality of light emitting areas disposed along a first direction to emit light, an optical scanner configured to scan the light emitted from the light emitter along a second direction that is different from the first direction, a light receiver configured to receive the light that is scanned by the optical scanner and then is reflected at an object, and a controller configured to divide a detection field into a plurality of subareas in a third direction that is orthogonal to the second direction, where a number of partitions of the detection field is variable.

An object detector comprising:
- a light emitter including at least a light source having a plurality of light emitting areas disposed along a first direction to emit light;
- an optical scanner configured to scan the light emitted from the light emitter along a second direction that is different from the first direction;
- a light receiver configured to receive the light that is output from the optical scanner and then is reflected at an object;
- and
- a controller configured to divide a detection field into a plurality of subareas in a third direction that is orthogonal to the second direction,
- wherein a number of partitions of the detection field is variable.
