摘要：
A collection of optical sub-elements can be arranged sequentially, such that they share a common optical axis through which light propagates. Each of these optical sub-elements can alter a phase, an amplitude, or a polarization of incident light, by virtue of its surface curvature, such as, for example, in a refractive optical element, or using microscale and nanoscale structures, such as, for example, in a diffractive optical element. One or more of these optical sub-elements can be rotated to tune one or more parameters, such as focal power, of the complete device.
