Abstract
Focused structured light fields with spatially nonuniform correlation can exhibit multiple focal points in the longitudinal direction, which suggests that they are suitable for longitudinal optical trapping. Due to the controllable nature of the longitudinal intensity distribution, this class of structured light fields not only can trap two high-index particles simultaneously, but also can manipulate them in the longitudinal direction.
