Abstract

Absolute measurement technique can separate the system error from the test results, so it's widely applied in the field of high-precision surface testing. For the testing process of three-position measurement technology is simple; it's often used for the measurement of spherical components. But three-position measurement technology is sensitive to the adjustment error. Therefore the multi-location average technology was proposed, which can reduce the influence of the adjustment error. A spherical component which diameter is 80mm and F number is 1.1 was used to test by the two technologies. Test results showed that: multi-positions average measurement technology can effectively reduce the influence of the adjustment error.
