Creating olfactory images is an attractive method for selective gas analysis. These images can be considered as response patterns of a sensor matrix, i.e. each pixel represents a signal from a separate sensor element. The vibrating capacitor (Kelvin) arrangement is a simple and accurate tool for measuring the adsorption-induced change of the work function at the surface of gas sensing layers. Olfactory images can be created using the scanning version of the vibrating capacitor probe equipped with computer imaging and image processing. This possibility is discussed in detail, and different olfactory images obtained by the scanning Kelvin method are presented.
