【Abstract】 A new method of generating two-dimensional symmetric optical trap array was presented. By controlling the optical trap position parameter and strength parameter of a pure phase modulation function,a transverse two-dimensional spatial optical trap array,the number,the location and relative intensity of any independent optical trap with arbitrary composing,could be obtained. The form board of phase distribution of a two-dimensional 3 × 3 symmetric optical trap array on the liquid crystal spatial light modulator( LC-SLM) was simulated by computer numerical calculation. The intensity distribution of the optical trap array was deduced.更多还原
