Optical lift apparatuses and methods thereof

摘要

A method for optical lift includes receiving illumination in a first direction on at least one of two different surface profiles of one or more cambered refractive objects. The one or more cambered refractive objects are rotated to a position of stable rotational equilibrium in response to the received illumination. The one or more cambered refractive objects are moved in a second direction non-parallel direction from the first direction.
