摘要

A rapid and cost-effective method for fabricating mini lens arrays is proposed. The lenses are made of silicone oil droplets and filled inside a polydimethylsiloxane (PDMS) elastomer. The lens array of different initial focal length and aperture can be fabricated by using the droplets of different volume. Due to good elastic behavior of PDMS, the droplet lenses can be flexibly deformed and focal length and numerical aperture can be tuned by applying an external force on the PDMS elastomer. Furthermore, an apparatus for focal length tuning is designed and employed in the imaging system.
