Abstract

In some recent studies, the microlens 2D array modulated by acoustic wave is firstly proposed and the capability to use it to design optical tweezers 2D array theoretically investigated, i.e., the dependence of its focal length and its numerical aperture on the thickness of the acoustic-elastic medium (AEM) is discussed. In this paper, the conditions for microparticle trapping as the maximum gradient force larger than the necessary force (> 0.01pN) and radius of trapping region satisfied the diffractive limit (Rtrap>l), are discussed to find out the suitable collection of parameters.
