In this paper, a method to design fiber bundle optical coupler is introduced. The structure of coupler is parameterized, and it could be optimized by coupling factor. The geometrical characteristics of coupler are circle-distributed, discrete and multi-layer. It is good for diffuse light collecting of grain sample with a large-diameter of incident beam.
