Abstract

Dispositif de filtre optique. Il est interposé entre un premier espace et un second espace entre lesquels on veut faire varier le pouvoir de transmission de lumière Un tel dispositif comprend deux feuilles transparentes renfermant un cristal liquide nématique, l'intervalle entre les feuilles étant compartimenté par des électrodes, des moyens étant prévus pour établir une tension électrique entre les électrodes.
