Abstract

The microlens array (MLA) scanning system is a relatively new solution for beam scanning, and are used in numerous applications, such as laser radar and optical communications. Excrescent light generated by overlapping divergent beams from adjacent microlenses increases with scanning angle and as a result, the rays do not fill the clear aperture of the MLA. The fill factor is proposed to characterize the fill rate of beams, and its effects on the point spread function (PSF) and modulation transfer function (MTF) are analyzed, this work can benefit the design and evaluation of MLA systems.
