The microlens array (MLA) scanning system is a relatively new solution for beam scanning. The excrescent light generated by overlapping divergent beams from adjacent microlenses increases with the scanning angle, and as a result, the rays do not fill the clear aperture of the MLA. The effect on the detection distance and imaging resolution of the MLA system are analyzed. Based on the principle of minimum spherical aberration, a design method for initial configuration of the MLA system is proposed. The findings of this paper can be beneficial for the design and evaluation of MLA systems.
