This article introduces a type of lens reflection section which makes use of laser light in connection with rough surface scattering to carry out methods for measuring the degree of roughness of high precision ball surfaces. The principles in this type of method are reliable. The design of the instruments is simple. Production costs are low. The environmental requirements are not high. Along with this, it is possible, on the presuposition that light path adjustments are not carried out, to carry out measurements on steel balls with different radii. It is suitable for checks at the production site. On the basis of the theory of light scattering, when a one beam unit strength straight laser beam is fired into a rough surface, the scattered light scatters into space toward various individual directions.
