- Abstract:
- In the Metrological laboratory for angle and length calibration, we are developing a new procedure for calibration of line scales. The line scale is scanned with a standard computer flatbed scanner. Distances between the lines on the scale are calculated as a product of measured number of pixels and the scale factor expressed in pixels per mm, while the scale factor is determined by a laser interferometer. The results show that this procedure complies with the accuracy requirements.
