Improved First Rayleigh Sommerfeld Method for Investigating Microlens Array with Long Focal Depth and Small f-number

摘要

cylindrical microlens array with long focal depth and small f-number, but the ORSMl is fully failure for those microlens arrays with small f-number. This investigation can provide valuable information for optical engineers and might be used for further guiding the designs of the micro-optical elements for realizing longitudinal optical field modulation.
