In this paper, we will present a developed framework of data processing for ultra-high precision MLT, such as 1 um minimum line/space. The underlying idea of the framework is to perform necessary preprocessing, such as scale and distortion correction, on polygon-based data format instead of pixel-based image format. In this way, the total amount of data could be greatly reduced. Furthermore, the on -the -fly scaling/rotation correction thus become possible, and therefore, higher resolution and precision correction can be achieved. In add
