High Performance Imaging System for Small Size Image Type Angle Displacement Measurement

Abstract

In the research of high resolution angle displacement measurement based on image detector, the amplification imaging of disc is the core of angle displacement measurement. Previous study has indicated that image definition severely affecting the resolution and precision of angle displacement measurement, in this paper, a high performance imaging system based on image angle displacement measurement is studied. It is a transmission-model lighting system, realizes the magnifies imaging of disc by short focal length lens and design adjustable focal length of mechanical structure. The system owes its small volume lightweight and high reliability, offers image angle displacement measurement with high performance magnifies imaging, provides the basis of high resolution angle displacement measurement technology.
