Abstract
A fluidic optical device, systems utilizing fluidic optical devices, methods for manufacturing fluidic optical devices and actuators are disclosed.
Claims19
An electrostatically actuated fluidic device, that is capable of providing a variable focal length lens, comprising:
- an elastic capacitor section;
- an elastic lens section in fluid communication with the capacitor section, the elastic lens section being characterized by a focal length;
- a fluid capable of fluid motion disposed at least partially in the capacitor and lens sections;
- wherein a voltage may be applied to the capacitor section causing it to deform;
- wherein the deformation of the capacitor section causes a portion of the fluid to flow into the lens section;
- wherein increase in volume of fluid in the lens section causes it to deform resulting in a variation in the focal length of the lens section.
