The turntable angle measurement principle is that the width of a grating line (an opaque area) of a grating is a, the width of a gap is b, the grating distance d=a+b, and generally a=b, which correspond to a certain angle value. The light source, counter, etc. are installed to the upper and lower positions of the grating scale to make the light source and counter rotate along with the standard part relative to the grating scale, and the counter can accumulate the number of rotated grating pitches to obtain the rotated angle value. Because the grating scale has no absolute degree, only the number count of the moving grating is accumulated, the grating scale is called an incremental grating scale, and the reading system is an incremental reading system.

The indication grating, the receiving tube and the luminous tube are fixed on the sighting part. As the scale moves with the collimator, moire fringes fall onto the receiver tube. For each rotation of the dial, the moire fringes move one revolution on the receiving tube and the current flowing through the receiving tube changes one revolution. When the instrument is aimed in the zero direction, the counter of the instrument is set at zero position, and when the dial is rotated along with the aiming part to aim at a certain target, the number of cycles of current flowing through the receiving tube is the number of gratings clamped between the two directions. Since the included angle between the gratings is known, the number of current cycles counted by the counter is processed to obtain the angle value of the display. If n pulses are uniformly interpolated in each period of the current waveform, the counter counts the pulses, and the number of the obtained pulses is equal to n times of the number of gratings clamped in two directions, which is equivalent to increasing the grating lines by n times, and the angular resolution is improved by n times. When the incremental grating dial is used for angle measurement, the rotation speed of the sighting portion is uniform, and the sighting portion cannot be suddenly or too fast, so that the counting accuracy is guaranteed.
