Abstract
E' descritto un apparecchio comprendente due sensori di luce piani disposti uno accanto all'altro. Un arresto della luce è distanziato da uno dei sensori di luce in posizione tale da arrestare o da schermare metà della superficie del sensore di luce da un raggio di luce proiettato, quando il raggio è ortogonale ad esso. L'altro sensore di luce è completamente esposto al raggio di luce proiettato. Il primo sensore di luce è esposto a più o meno del raggio luminoso in funzione dello scostamento del raggio, in una direzione o nell'altra, dall'ortogonalità al piano del primo sensore di luce. Un rapporto tra il segnale in uscita dal primo sensore di luce ed il segnale in uscita dal secondo fornisce l'informazione relativa all'angolo del raggio rispetto al piano del primo sensore di luce.
