Abstract:

The structure and working principle of an integrated optical-fiber proximity sensor that detects both the distance and the orientation and possesses the function of self-compensation are introduced in this paper. The corre-sponding decoupling approach to the sensor is then presented based on the muhiscale characteristics. The decou-pling process can be divided into two parts:classifying the information based on the muhiscale degree and solving the coupling equation via the computational approximation methods with different precisions. The principle,physi-cal meaning and implementation process of the approach are finally discussed,indicating that the proposed ap-proach is so real-time and precise that it can be applied to other similar circumstances.

Key words: robot, optical-fiber proximity sensor, decoupling, muhiscale characteristic
