LASER SENSOR, MIRROR CONTROL METHOD, AND PROGRAM

In a laser sensor for two-dimensionally scanning an object to be measured by scanning a scanning angle range, a field angle parameter correction circuit (20) is provided with: a field angle change detection unit (201); an input unit that inputs a scanning angle range set on the basis of the distance to the measurement object and the azimuth angle and an offset amount of the scanning angle range in the vertical direction, and outputs a signal indicating a changed first frame and an offset change amount when a change in the field angle is detected on the basis of the input offset amount; and a correction amount generation unit (202) that uses the offset change amount to generate an offset correction amount and a scanning angle range correction amount corresponding to an assumed offset amount of the first frame, and adds and outputs the offset amount and the offset correction amount in the first frame in response to a signal indicating the changed first frame, and outputs the offset amount and the scanning angle
