Abstract
In this paper, the measuring accuracy about the angstrommeter is searched, and a special measuring method about the thickness of the optical coating is developed. A "fully assembling optical coating block" is used successfully. It consists of three kinds of optical coating from which 7 sorts of thickness can be formed. Properly choosing the arrangement model, we can composs 19 coudition equations. According to the theory of matrix square-error, we deduced the measuring accuracy of the coating thickness and the measuring accuracy of the interferometer itself. The method is also useful for some other films.
