Abstract

Potentiomètre optique réglable par levier de commande. Le potentiomètre optique comprend une première et une seconde fenêtre de transmission de lumière variable, une source de lumière pour envoyer de la lumière d'un côté des fenêtres, un premier et un second dispositif photosensible montés de façon qu'un seul d'entre eux reçoive de la lumière à n'importe quel moment, et des moyens pour déplacer relativement les première et seconde fenêtres et les premier et second dispositifs photosensibles. Application à la génération d'un courant alternatif ou continu.
