LASER SCANNER, LASER SCAN SYSTEM AND LASER SCAN METHOD

摘要

PROBLEM TO BE SOLVED: To provide a laser scanner, a laser scan system, and a laser scan method, capable of measuring a three-dimensional shape of a measurement object by a light-section method without using a mechanical motion mechanism.SOLUTION: The laser scanner comprises: a light source 2 for emitting a laser beam L1; a light-sending collimator 3 for receiving the laser beam L1, and emitting the laser beam L1 as slit light L3 the irradiation range of which expands in a height direction D1; a direction changing section 4 for receiving the slit light L3, and emitting the slit light L3 in an angle according to the wavelength of the slit light; and a wavelength adjustment section 5 for continuously changing the wavelength of the laser beam L1.
