Abstract

In this paper, based on the collaborative integration and modeling calculation of single-point Laser Doppler Vibrometer (LDV), a 3D oblique non-contact dynamic attitude measurement system is proposed. By using two groups of three-dimensional measurement devices which consist of three LDVs, our system can measure the translation and rotation of the measured object. The experiments are carried out under line vibration environment, and the elicited results are compared to those elicited using fiber optic gyroscope (FOG), which verified the feasibility of our system.
