Abstract

Insufficient vision information such as occlusion, low resolvability, and a small field of view (FOV) represent important issues in microassembly and micromanipulation. In previous research, an active optical system was designed to supply a compact flexible view. However the complex kinematics makes the system operation and calibration much difficult. In this paper, a decoupling design for the variable view image system with a telecentric lens group is proposed to decouple the view angle and scanning mirror angle. The proposed design increases the range of zenith angle. The forward kinematics is analyzed with the help of vector diffraction theory. The singularity of Jacobin is analysis and the singularity configurations are identified. In order to verify the proposed system, a prototype system is built up. A series of experiments on the prototype system shows the validity of the new design.
