A Simple and Long-Range Displacement Measurement System

Abstract:

This paper introduces a well-used long range displacement measurement system. The advantages of the system are that the sensor's measurement range can be extended by optical linear scale with a simple structure, and the distance between the measured object and the sensor can be automatically adjusted. The feasibility of the measurement system is tested by simulation experiments, and the accuracy performance is evaluated with respect to both repeatability error and linearity error. The experimental results show that the displacement measurement system reaches a level of accuracy which is sufficient for operational requirements.
