Tips: Linear scale working principle

Transmission grating, for example, when the indicator on the grating lines and scale on the grating lines formed between a small Angle theta, and two relative of parallel grating ruler facets, in under the irradiation of light source, is located in a nearly vertical grid lines, the formation of light and dark stripes. This stripe is called the moire stripe. Strictly speaking, the direction of the moire fringe is perpendicular to the bisector of the Angle between the two grating lines. The distance between two bright or dark lines in the moire fringe is called the width of the moire fringe, denoted by W:
W is /2 times sine of over 2, which is/over 2.
