Abstract

Dispositif à cellules photovoltaïques, en particulier pour systèmes de mesure de position incrémentaux ou numériques absolus, dans lequel à chacune des deux entrées d'un premier amplificateur différentiel est raccordée une cellule photovoltaïque à laquelle une résistance est montée en parallèle. Il est prévu un second amplificateur différentiel 7 monté en contre-réaction et à l'entrée non inverseuse duquel est raccordée une cellule photovoltaïque 8 à laquelle une résistance 9 est montée en parallèle et les cellules photovoltaïques 3, 4 reliées aux entrées du premier amplificateur différentiel 2 et la cellule photovoltaïque 8 sont raccordées en parallèle à la sortie du second amplificateur différentiel 7.
