PROBLEM TO BE SOLVED: To obtain accurate measurement of a long multi-beam and high output laser profile and a near field pattern, in particular light intensity, efficiently in a short period of time, enabling fetching a series of data with easy adjustment to an object and a low equipment cost, eliminating a defect in the conventional measurement method using a CCD camera.SOLUTION: Light emission from a plurality of laser diodes mounted in juxtaposition on a fixed tabular base is scanned by sliding a slit formed of opposite edges of a pair of tabular body, to receive the light by a light-receiving device and calculate. |
