Abstract
We present a microlens arrays (MLAs) based artificial compound eye for tuning a focal length. The flexible MLAs-patterned poly (dimetylsiloxane) (PDMS) film was deformed from planar to curved shape with the increase of the fluid injection, acting as a focus-tunable lens. With a designed optical system, we compared focused beam intensity depending on the radius of curvature of the fabricated lens.
