摘要：
A scan beam light quantity distribution method and apparatus using a two-dimensional area light receiving sensor (8) movable in the same direction as scan direction of a scan beam. The two-dimensional area light receiving sensor (8) detects a scan beam while moving in the scan direction of the scan beam. The scan beam received by the two-dimensional area light receiving sensor (8) is correlated with position information when stored in data storage section (10.) By using scan beam data stored in the data storage section, analysis is made on a light quantity distribution of the scan beam scanned in X-direction.
