Then, the first hand-held part 12 is rotated to the first and last positions of the three equal standard metal linear rulers, and whether the longitudinal line of the cross division line in the CCD lens 16 is overlapped with the scale lines of the first and last positions (0 scale line and 1000 scale line) of the three equal standard metal linear rulers is observed on the display of the controller 18. If the measured values do not overlap, the result shows that a certain Abbe error exists between the scale horizontal line of the three standard metal linear rulers and the measuring axis of the laser interferometer 2. At the moment, the relative positions of the three equal standard metal line rulers are adjusted by screwing in and out the adjusting screws 8 at the two sides so that the longitudinal line of the cross division line is superposed with the scale marks at the head and tail positions of the line rulers. As shown in FIG. 5, the cross differentiation line 18-3 of the three-level standard metal linear ruler was adjusted from 18-1 to 18-2.
4. And reading and calibrating the scale line indication values of the three-equal standard metal line ruler by the movable platform. Here, taking a 0.2mm reticle plane as an example, a reading calibration process of the reticle indication value is explained: first, the first hand-held portion 12 is turned to the vicinity of the 0mm scribe line of the third and the same standard metal rulers by coarse displacement adjustment. Then, fine adjustment of displacement is performed, the second hand-held part 14 is rotated to completely coincide the vertical line of the cross-shaped division line of the CCD lens 16 with the 0mm scale line, and at this time, zero setting operation is performed in the measurement software of the laser interferometer 2. According to the relevant regulation of calibration ruled lines in the national metrological verification regulation JJG 71-2005, the third-class standard metal linear ruler, the first handheld part 12 and the second handheld part 14 are sequentially rotated to move the longitudinal lines of the cross division line to positions of 100mm, 200mm and 1000mm, and the indication values of the laser interferometer 2 at the positions are respectively read, so that the scale line calibration indication value errors of the third-class standard metal linear ruler are the difference between the scale line readings of the third-class standard metal linear ruler and the indication values of the laser interferometer 2.
