| Abstract: | High-quality Moire fringe signal is obtained by a self-imaging system consisting of a 690nm semiconductor laser, collimating lens, photoelectric receiving elements and fine gratings according to grating self-imaging principle. The fine grating photoelectric shaft encoder based on the Moire fringe signal has the advantages of high accuracy, high response frequency and easily realized miniaturization. The technique is a new and practical solving approach for improving angle-measuring and environmental adaptability of the photoelectric shaft encoder. |
