Title (EN) LIQUID LENSES
(FR) LENTILLES LIQUIDES
Abstract:
(EN) A liquid lens can have a chamber configured to improve the performance of the liquid lens, such as by improving the tilt response time and/or by reducing optical aberrations. The chamber can have sidewalls that conform to a shape of a truncated cone. The cone angle, and wide end diameter, and narrow end diameter can be selected by balancing competing factors. The liquid lens can include two fluids, and the fluid fill ratio can be selected to improve the performance of the liquid lens. In some embodiments, the sidewalls can conform to a portion of a sphere.
(FR) Une lentille liquide peut comporter une chambre conçue pour améliorer les performances de la lentille liquide, par exemple en améliorant le temps de réponse d'inclinaison et/ou en réduisant les aberrations optiques. La chambre peut comporter des parois latérales qui épousent une forme de cône tronqué. L'angle, le diamètre de l'extrémité large et le diamètre de l'extrémité étroite du cône peuvent être sélectionnés en équilibrant des facteurs contradictoires. La lentille liquide peut contenir deux fluides. Le rapport de remplissage des fluides peut être sélectionné de façon à améliorer les performances de la lentille liquide. Dans certains modes de réalisation, les parois latérales peuvent épouser une partie d'une sphère.
