Abstract
A light detector according to an embodiment includes a light receiver and a controller. The light receiver includes sensors and pixels. The sensors are arranged two-dimensionally on a substrate. The controller is configured to set a light-receiving region in which the sensors are selectively turned on in the light receiver. The controller sets first and second light-receiving regions. The first and second light-receiving regions include first and second pixel, respectively. The second light-receiving region is arranged away from an optical axis of laser light received by the light receiver. The controller, after turning on each of the first pixel and the second pixel, is further configured to turn off the second pixel in a state in which the first pixel is turned on.
