摘　　要：为探究fNIRS在飞行员脑力负荷测量领域的适用性,本研究概述了其应用现状,并基于模拟飞行场景应用该技术进行模拟飞行实验。招募18名航线飞行员作为被试,通过在A320模拟驾驶舱设计并实施低能见环境下的模拟飞行任务,应用f NIRS设备记录被试前额叶皮层下含氧血红蛋白浓度、脱氧血红蛋白浓度及总体血红蛋白浓度,PPG传感器记录心率和心率变异性指标。结果表明低能见环境出现后,飞行员含氧血红蛋白浓度增加,脱氧血红蛋白浓度降低;HR和HRV指标未体现出相应变化。可见fNIRS技术作为一项前沿技术,在反映脑力负荷及相关认知活动方面表现出敏感性,可应用于飞行安全与人因研究,包括开展模拟飞行场景的飞行员选拔、训练以及未来驾驶舱设计研究。In order to explore the applicability of fNIRS in the field of pilots'mental workload measurement,this study summarizes the progress of fNIRS technology,and applies this technology to simulated flight experiments based on simulated flight scenarios.18 airline pilots were recruited as subjects.The simulated flight mission under low visibility environment was implemented through the design of A320 analog cockpit.The concentration of oxyhemoglobin,deoxyhemoglobin and total hemoglobin under the prefrontal cortex of the subjects were recorded with fNIRS equipment,and the heart rate and heart rate variability were recorded with PPG sensors.The results showed that the concentration of oxyhemoglobin increased and the concentration of deoxyhemoglobin decreased in pilots after low visibility environment appeared;HR and HRV indicators did not reflect corresponding changes.It can be seen that as a cutting-edge technology,fNIRS technology shows sensitivity in reflecting mental workload and related cognitive activities,and can be applied to flight safety and human factors research,including pilot selection and training in simulated flight scenarios and future cockpit design research.
