摘要： A method for correcting scanning errors in a shuttle type of a scanner, including the steps of scanning a pattern sheet on which pattern data having a specified shape are recorded. Errors for decline of the pattern data are corrected by using the pattern data having a straight line among the scanned pattern data having the specified shape. Then, errors for distance between bands are corrected by using the pattern data having the specified shape among the pattern data of which the errors for decline are corrected. Accordingly, since the errors for decline and the errors for distance between the bands can be corrected by using a computing program, there is an advantage in that correcting the errors of the pattern data is very simple. A further advantage is in that even if the scanner is subjected to an impact from its exterior, correcting the errors for decline and the errors for distance between the bands can be promptly performed.
摘要翻译：一种用于校正梭式扫描仪中的扫描误差的方法，包括扫描记录了具有指定形状的图案数据的图案片的步骤。通过使用具有指定形状的扫描图案数据中具有直线的图案数据来校正图案数据的下降的错误。然后，通过使用校正了下降误差的图案数据中的具有指定形状的图案数据来校正频带之间的距离误差。因此，由于可以通过使用计算程序来校正衰减的误差和带间的距离误差，所以存在校正图案数据的误差非常简单的优点。另一个优点在于，即使扫描仪受到来自其外部的冲击，可以迅速地进行校正下降的误差和带间距离的误差。
