Abstract

A variable focal length lens sensor system for use with UAVs is disclosed. A variable focal length lens camera for use with cell phones. One or more static optical components and one or more are within a housing. The variable focal length lens includes a sidewall and first and second optical surfaces defining an aperture. One or more of the optical surfaces are at least partially elastic. One or more lens fluids are disposed between the aperture and sidewall. An actuator is configured to apply a force to a portion of the variable focal length lens. The applied force results in a change in focal length of the variable focal length lens. The combination of static optical components and variable focal length lenses are capable of providing variable zoom and focus. An image sensor is optically coupled to the variable focal length lens for capturing images. Control electronics are configured to control the fluidic lens and sensor.
