| Abstract: | A new method for accurate thickness measurement is introduced. On the basis of the principle of active trigonometry with the vertically incident mode, an aslant incident mode is proposed. The method is specially designed for a reflective surface of an object, such as a thin steel plate, to measure its thickness in real time with high accuracy. The influence of the small deflexion by vibration on the object's surface which would add to the result is discussed, and the manner to reduce this influence is also given. |
