Abstract

To comprehensively analyze and evaluate the combat effectiveness of the incoherent intense light, it is necessary to obtain the distance of the glare effect caused by incoherent intense light. Firstly, by applying the nominal ocular dazzle distance model proposed by Williamson, numerical calculations were conducted to determine the glare effect distance of intense light with an illuminance of 1.2×10⁶ lx, an aperture size of 0.42 m, and a beam divergence angle of 26 mrad. The obtained results reveal the glare effect distances of a single incoherent source under different background light levels and atmospheric visibility conditions. Secondly, based on the model proposed by Mlynczak, which involves multiple intense light sources simultaneously illuminating the human eye, the glare effect distances of multiple incoherent sources under different background brightness levels and incident angles were calculated. Finally, a sensitivity analysis was conducted to assess the impact of nine factors on the distance at which the glare effect caused by incoherent intense sources. The results indicate that factors such as background brightness, atmospheric visibility, illuminance, divergence angle and incident angle have a significant impact on the glare distance of incoherent intense light.
