摘要： A method and apparatus for control of optical trap arrays and formation of particle arrays using light that is in the visible portion of the spectrum. The method and apparatus provides a laser and a time variable diffractive optical element to allow dynamic control of optical trap arrays and consequent control of particle arrays and also the ability to manipulate singular objects using a plurality of optical traps. By avoiding wavelengths associated with strong absorption in the underlying material, creating optical traps with a continuous-wave laser, optimizing the efficiency of individual traps, and trapping extended samples at multiple points, the rate of deleterious nonlinear optical processes can be minimized.

摘要： An apparatus and method for manipulating, effecting interaction of, photochemically transforming and/or sorting small dielectric particles or other materials are disclosed. The apparatus and method involves the use of one or more diffractive optical elements which each receive a laser beam and form a plurality of laser beams. These laser beams are operated on by a telescope lens system and then an objective lens element to create an array of optical traps for manipulating, effecting interaction of , photochemically transforming and/or small dielectric particles or other materials. One object of the invention is to provide an improved method and system for using optical traps to incorporate foreign matter into living cells. Another object of the invention is to provide an improved method and system to sort optically nonabsorbing particles from optically absorbing particles. Yet another object ot the invention is to provide an improved method and system to implement the fabrication of heterogeneous structures using spatially resolved photochemistry.
