An outer surface of a casing (100) is provided with a first shape portion (152) and a second shape portion (154). The first shape portion (152) and the second shape portion (154) are engageable with other shape portions located outside the casing (100). The first shape portion (152) and the second shape portion (154) are aligned on the same straight line as a virtual straight line passing through the center of a field of view when viewed from a direction perpendicular to a direction in which the field of view expands. Alternatively, the first shape portion (152) and the second shape portion (154) may be aligned along a direction parallel to this straight line when viewed from the direction perpendicular to the direction in which the field of view expands.

A detection device of a light detection and ranging (lidar) device, a detection method, and a lidar device are provided. The detection device predicts the location of light spots of a reflected echo on a detector array, and reads electric signals of a subset of the photodetectors corresponding to the light spots.
