Paper Abstract

Insufficient vision information due to occlusion and low resolvability is one of the important issues in conventional optical vision system that limits its application in micromanipulation and microassembly. The variable view imaging system can help prevent these issues by changing optical system parameters such as spatial position, orientation and focus plane. Its ability to achieve desired view of the target makes it particularly suitable for observing three dimensional micro objects in micromanipulation and microassembly. In order to determine the tilt angle, pan angle and view position, the kinematics of the variable view system was analyzed based on the ray tracing analysis with the help of the vector refraction theory. This paper also shows its applicability in microassembly by demonstrating micro peg-in-hole insertion task.
