Paper Abstract

In many cases the physical properties measured using sensing elements require to multiply one of them by another. The multiplication can be realized in many ways, and in presented paper an optoelectronic system multiplying the electric signals, composed of electroluminescent diodes and photoconducting elements, is proposed. In the proposed system the linear range of the dependence of the luminance of electroluminescent diode on the current and the linear dependence of the conductance of photo-conducting element on the illumination are utilized. The output signal from the multiplying system can be an electric signal, or in another version can have the shape of a light signal, sent on by an optical fiber.
