新一代飞行头盔夜视用传感器分析

Analysis of Night Vision Sensors Integrated in New Generation of Flight Helmet

合适的夜视传感器对于飞行头盔的设计至关重要,是确保飞机驾驶员完成任务的关键。飞行头盔的工作特点也决定了集成其上的夜视传感器必须具备高灵敏、紧凑轻便等特性。在分析飞行头盔用夜视传感器的工作环境、目标特性基础上,参照已集成应用于飞行头盔的夜视传感器实例,解析了两种适用夜视传感应用的“电子轰击混合型像增强器”和“InGaAs焦平面型探测器”的技术指标。给出了适合飞行头盔用夜视传感器的主要技术指标要求,并提出对国产现有夜视用传感器加以改进,使之更适合飞行头盔夜视应用的技术方向。

Choosing a suitable night vision sensor is key to ensure a good design of flight helmet and to ensure a flight task completion for pilots.The operating characteristics of flight helmets also require that the night vision sensors integrated into them be highly sensitive,compact and lightweight.On the basis of analyzing the working environments and target characteristics of night vision sensors for flight helmets,and with reference to the examples of night vision sensors that have been integrated and applied to flight helmets,the technical specifications of two kinds of"electron bombardment hybrid image enhancers"and"InGaAs focal-plane detectors"were analyzed that were suitable for night vision sensing applications.The main technical requirements was given for night vision sensors suitable for flight helmets,and the technical direction of improving the existing domestic night vision sensors was put forward to make them more suitable for night vision applications in flight helmets.
