| Abstract: | The effect of aperture on optical limiting was analyzed and calculated in two typical optical-systems.The investigative parameters included aperture size and position.The optical systems were ideal telescopic system and ideal focusing system.The calculations were based on Z-scan theory and its modified formulas;the optical-limiting mechanism was nonlinear refraction.In each situation,the effect was analyzed qualitatively and the corresponding numerical curves were gained.This investigation is useful in optimizing and selecting aperture of optical limiters |
