  • Systems and methods for effecting zoom and focus using fluidic adaptive lenses
    Patent number: 7986465
    Abstract: Fluidic lens devices, and systems employing such lens devices, along with methods of fabricating and operating such lens devices, are disclosed. Certain of the disclosed structures permit fluidic lens devices to operate without valves that control fluid exchange between fluidic lenses and reservoirs. Also disclosed are fluidic lens devices that comprise a fluidic lens but no reservoir. Additional disclosed structures and methods permit fluidic lens devices to perform zoom and focus functions.
