Claim 6:
7. A light detector comprising:
a light receiver including a plurality of sensors arranged two-dimensionally on a substrate; and
a controller configured to:
set an overall light-receiving region in which the sensors are selectively turned on in the light receiver; and
set a first light-receiving region of the overall light-receiving region and a second light-receiving region of the overall light-receiving region different from the first light-receiving region, based on coordinate information input from outside the light receiver,

wherein the second light-receiving region is arranged to be further away from an optical axis of laser light received by the light receiver than the first light-receiving region,
wherein the width of the second light-receiving region in a first direction in which the first light-receiving region and the second light-receiving region are adjacent to each other, is greater than the width of the first light-receiving region in the first direction, and
wherein the width of a portion of the second light-receiving region in a second direction intersecting the first direction is narrower than the width of the first light-receiving region in the second direction, the portion of the second light-receiving region being turned on.
