【摘要】 目的探讨不同环境光条件下飞行员认读夜视兼容绿光LED导光板字符的适宜亮度,尝试建立夜视绿导光板的自动亮度曲线模型。方法以108名战斗机飞行员为受试者,构建亮度可调的LED夜视兼容导光板和LED模拟环境光源作为实验设备。在每一档环境照度条件下,受试者分别调节出认读导光板字符所需的最低亮度、适宜亮度和所能耐受的最高亮度。结果初步建立了P5、P50和P95百分位飞行员最低亮度、适宜亮度和最高亮度的自动亮度曲线模型。结论本文建立的飞行员自动亮度曲线模型的工程化应用,尚需用户的使用性验证,并对曲线模型进行微调或修正。更多还原

【Abstract】 Objective To explore the optimal brightness of night vision imaging system compatible green LED integrally illuminated information panels when pilots are reading in different ambient illuminance,and attempt to build the auto brightness curve model.Methods One hundred and eight fighter pilots served as the test subjects.A LED panel and a LED lamp were used in the experiment.In every level of the simulated brightness,pilots were asked to adjust the lowest brightness,the optimal brightness and the highest brightness while reading characters on the LED panel.Results By means of the experimental exploration when 108 pilots reading the characters on LED integrally illuminated information panels,the auto brightness curves models of the 5th,the 50th and the 95th percentile pilots are founded.Conclusion The engineering application of these models founded by this paper needed to be verified by the users,and might be rectified according to the verification.更多还原
