A SMART SENSING METHOD FOR DISCRETE DISPLACEMENT MEASUREMENT

Bruno Andò, Salvatore Graziani, Nicola Pitrone

Abstract

In this paper a new displacement sensing device, based on both a new sensor topology and a smart signal processing is discussed. The main feature of the proposed system is its insensitivity to both the target material and the influence parameters (e.g. light condition). As an example, the sensor can be minded as a useful tool for visual impaired people, to help their navigation in unknown place, being (for this purpose) the material-free feature much more important than the resolution. Moreover, the developed device has the advantage to be a low cost system.
