Zusammenfassung:	PROBLEM TO BE SOLVED: To enable high-speed measurement in a three-dimensional area and to prevent deterioration of measurement accuracy caused by stray light.SOLUTION: The laser sensor device includes a light shielding unit for dividing the inside of a housing case for housing a polygon mirror 3 into a first space from a laser projector to the reflection surface of a polygon mirror 3 and a second space from the reflection surface of the polygon mirror 3 to a receiver, a first scanning unit 4 for rotating the polygon mirror 3 to scan a measurement laser beam in a first direction, and a second scanning unit 5 for rotating the polygon mirror 3 around a center axis crossing the center axis of the rotation by the first scanning unit 4 to scan the measurement laser beam in a second direction crossing the first direction.
