Abstract
A control system with a chip of 8031 single-chip microcomputer as its nucleus for a diffraction grating ruling engine has been developed, its hardware and software are presented in this paper. A series of techniques such as program-controlled amplifier and interference fringes subdivision as well as motor velocity step governing are adopted to improve the control accuracy. With this control system, 8 kinds of gratings of different spacings can be ruled, the positioning precision of the diffraction grating ruling engine (sigma) equals 3.6 nm, and the maximum positioning error is less than 14.6 nm.
