Yes. The dune staple for remote viewing seems to have a bit more of science i thought. New Scientist tech reveals that The first liquid camera lens with no moving parts, and that can switch between two levels of magnification, has been designed by a German research team. The work is an important step towards liquid zoom lenses that can sweep through a range of magnifications.
Liquid lenses bend light using the curved boundary between watery and oily liquids. When the two liquids are held in the right container, the boundary between them can be made to curve in a way that focuses light simply by applying a voltage.
Liquid lenses have attracted much attention because they are potentially smaller than conventional optics and cheaper to build. Samsung has already built them into some cellphones.
But the greatest savings in size and cost can be made with zoom lenses. Altering the focusing power of a set of liquid lenses should provide the same effect as changing the distance between solid, fixed-focus lenses in a traditional zoom lens.
