Abstract

Direction sensor based on photovoltaic effect. The present invention relates to the detection of angular position adopted by the support of the sensor with respect to a light source. The detection of direction with respect to the said light source is due to the potential difference generated by the photovoltaic sensor when the light is incident on both of its faces. It consists alternatively of two or of four photovoltaic cells arranged in a pyramid shape, such that the photovoltaic energy generated by each two opposed faces is compared by a differential amplifier, the result of which is a voltage indicating the angular offset of the light source with respect to the bisector formed by the plane of symmetry which joins the vertex to the pyramid base. The voltages from both differential amplifiers indicate the coordinates, in two degrees of freedom, of the position of the light-emitting focus or the offset of the focus with respect to the trajectory normal to the base which passes through the vertex of the photo- detecting photovoltaic pyramid. The characteristic of the present invention lies in the fact that each photo-detector panel generates an electrical voltage proportional to the light picked up, and the light picked up is a function of the direction of the cells with respect to the light focus.
