英文摘要: Following polar cordinate mesuring method with single apparatus, and combining precise laser ranging technology and high-accuracy angular measure technology, Laser tracker have excellent ability in large-scale metrology. Angular mesure system adopt with rotory grating, which is a non-contacat digital measure system integral with optical, mechanical and electronic technology. Accompanied with simple structure, high precision and fast measure speed, rotory grating have widespread used in epuipment of precision angular measurement. According to analysis all type error of rotary grating such as dividing error in manufacture, subdivision error in electroncis, wobbling of shaft and eccentricity of grating in mounting, a error compensation model were established through Fourier analysis method, adopted this compensation, the angular error reduced form 10 arc-second to 0.8 arc-second measured by one grating readhead, this measuring accuracy correspondent to diametrical measurement by two grating readhead, which characteristic ultra-high accuracy of 0.3 arc-second. © 2015, Editorial Office of Chinese Journal of Scientific Instrument.
