    • High quality images are provided without the occurrence of image quality defects due to reciprocity law failures, even when scanning a multi-beam. When interlaced scanning is employed, it is possible to select combinations such that, taking any freely selected neighboring scanning lines, respective scan numbers of the neighboring scanning lines are always different. Thus, a duration of scanning spacing can be made to be at least the duration of a single main scan. As a result, image defects such as banding due to reciprocity law failures can be greatly alleviated, and images can be provided in which image defects are to unlikely to be noticed in practice.
    • 即使扫描多光束,也可以提供高质量的图像,而不会由于互易定律故障而出现图像质量缺陷。 当采用隔行扫描时,可以选择组合,使得采用任意自由选择的相邻扫描线,相邻扫描线的相应扫描编号总是不同的。 因此,扫描间隔的持续时间可以至少是单个主扫描的持续时间。 结果,可以大大减轻由于互易定律失败引起的诸如条带的图像缺陷,并且可以提供图像缺陷在实践中不太可能被注意到的图像。
