一种应用于反射表面厚度测量的新方法

A New Method Applied in Thickness Measurement on Reflective Surface

讨论了垂直入射与斜入射两种方式的主动式三角法的测量原理，提出在被测物面为反射表面的情况下，用斜入射主动式三角法进行距离和厚度的测量．分析了被测物表面细节形状的变化对测量结果的影响。

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.
