【Abstract】 This paper simply presents the measure principle of grating signal with moiré fringe. It also analyses the composing and the work principle of discerning direction and subdivision circuit about grating signal with moiré fringe based on DSP TMS320C240.The circuit has been realized eight-subdivision of grating signal with moiré fringe, and it improved greatly resolution of detection system on the worktable location.更多还原
