摘要:
A hybrid lens includes a transmissive adaptive liquid lens and an optical element including liquid crystals. The adaptive liquid lens includes a layer of optical fluid on a substrate. A focal length of the adaptive liquid lens is adjustable. The optical element including liquid crystals is optically coupled with the adaptive liquid lens. The optical element including liquid crystals is configured to adjust a refractive index across the optical element including liquid crystals in conjunction with adjusting the focal length of the adaptive liquid lens so that the optical element reduces optical artifacts caused by the adaptive liquid lens.
