Currently, laser technology has become increasingly mature. Semiconductor lasers have the characteristics of small size, long indication distance, life, and low cost. Therefore, many studies regard them as launching devices monitoring system fix at points structures to reflect displacements through spots produced by them. However, this method also exhibits a drawback, that is, can only be applied case where displacement is generated point no rotation angle generated. If occurs point, spot caused coupling effect which will affect results significantly. In article, proposed decouple eliminate influence sufficiently, projecting onto two screens. This significantly improve application scope provide possibility for its in practical engineering.
