Patent

CA 2758206

Liquid lens cells are used in a variable power optical system. In one embodiment, a stop is located between a first lens group comprising at least a first liquid lens cell and a second lens group comprising at least a second liquid lens cell. In one embodiment, a liquid lens cell controls an incident angle of light rays on an image surface.

Selon l'invention, des cellules de lentille liquide sont utilisées dans un système optique à puissance variable. Dans un mode de réalisation, un arrêt est situé entre un premier groupe de lentilles comprenant au moins une première cellule de lentille liquide et un second groupe de lentilles comprenant au moins une deuxième cellule de lentille liquide. Dans un mode de réalisation, une cellule de lentille liquide commande un angle d'incidence de rayons lumineux sur une surface d'image.
