ERP 880 angle encoder features small reversal error and increased resolution making it especially suitable for such applications as small measuring stages and ultra-precision machine tools. Incremental angular device is equipped with a circular scale with 90,000 grating periods. Graduation is scanned interferentially so that after signal acquisition, 180,000 sinusoidal signal periods are available for evaluation. At its optimum, system accuracy is
