A dynamic array of optical traps for deformation of elongated microobjects
- 14 Downloads
A simple technique for the formation of an array of laser traps on the basis of phase diffraction gratings is proposed. The array allows trapping transparent elongated microobjects at several points simultaneously. The dynamic variation in the spatial disposition of the traps makes its possible to impose deformation on a trapped microobject. The technique proposed has been experimentally tested.
