A Grating-Based Dynamic Measuring Method of Small Three-Dimensional Angles

Abstract:

Based on the diffraction theory of the one-dimensional gratings at oblique incidence, by introducing the laser autocollimation system, a novel approach of dynamically measuring small angles with three degrees of freedom is proposed. By matrix transform, a mathematical model is established to describe the changes of small 3D angles as a function of the variation of the image position of the diffraction spot, and the solution of this model is demonstrated. A prototype machine has been made to verify the practicability of the measuring method proposed. Analysis of the measuring range and resolution of the system shows that within the range of ±1.6 degrees.
