Abstract
The technology of a microlens array scanner (MLAS) has the potential to realize large-angle beam scanning with a large beam size. Two sets of microlens arrays (MLAs) were used as phase-controlling emitters in MLAS. A mathematical model of the MLAS with Kepler structure was established in the desired direction and leakage direction. It was verified that the maximum relative displacement of MLAS was half of the MLA sub-aperture. Two sets of F/5 continuous surface MLAs were used as emitters in the experiment. One-dimensional discrete-addressing scanning process with $\sim{10}^\circ$ field of view is demonstrated, and it is in good agreement with the theory.
