Centering of the Screening Patterns and Code Wheels of Angular Movement Photoelectric Converters by Means of an Annular Hairline and Scale Lines

Methods of centering scanning patterns by means of a centering circle and scale lines are analyzed. It is shown that centering with respect to scale lines using two reading systems situated in diametrically opposite parts of the scanning pattern is the most accurate method.
