In order to achieve rapid and accurate measurement of sphere bearing ball during manufacturing process, a set of Michelson interferometer measurement system was proposed based on white light interferometer technology, image processing technology and signal processing technology. White light interferometry technique was analyzed theoretically. The precision and roughness measurement of the optical spherical radius of sphere ball bearing were made. The finish resolution image and the curvature radius image were obtained. The accurate calculation data was obtained after processing a large number of experimental data. The finish resolution can reach the nm level and the curvature can be calculated to the μm level. The processing quality and the detection speed are improved.
