A method for transporting and rearranging mesoscopic objects in three dimensions using short repetitive sequences of holographic optical trapping was demonstrated. Implementation of optical peristalsis incorporated imaging and the flexibility afforded by a computer-addressed spatial light modulator. It was found that comparable transport could be achieved by cycling mechanically through a sequence of microfabricated diffractive optical elements.
