Paper Abstract

Considered is a correlation method of forming of specified distribution of radiation energy over the target, particularly in the optical tweezers wand. The method exploits an interaction of beforehand spatially modulated in phase wand beam with synthesized hologram specific to the modulation. The specified energy distribution is obtained as the convolution of the required field distribution and of cross-correlation function of the ideal wand beam and the real one. Because of beams wave fronts modulation the result of such a convolution is weakly dependent on the difference of the ideal and the real beams. Examined is the possibility of dynamic operation mode involving the spatial light modulation (SLM) device.
