Paper Abstract

In-situ measuring the intensity and characteristics stresses in optical coatings during deposition can get a lot of important information for improving the properties of optical thin films, which is more important for some devices uesd in modern science and technology. This paper gives a new method which uses a kind of most in-fashion sensing technology, a single-mode optical fiber sensing system developed in the middle of 1900s to test the stresses in optical coatings during deposition with the aid of a single-chip micro-computer and a micro-printer. The experimental results show that this method takes advantages of high sensitivity wide dynamic range, small volume, available in-situ measurement and easily interfaced to any vacuum system.
