摘要
分析了直升机飞行员头盔夜视系统的视觉特性,分析了视场、重量、像质、眼点距离、出瞳直径等主要影响视觉舒适性的技术指标,提出了使用塑料元件减重、合理增大眼点距离和出瞳直径等指标,以及增大视场的两种方案,可作为相关设计的参考。
In this work, we have analyzed the visual characteristics of the helmet-mounted night vision system for helicopter pilots, with special focus on the field of view, weight, image quality, eye relief, exit pupil diameter, and other technical indicators that mainly affect visual comfort. We propose the use of plastic components to reduce the weight, a reasonable increase of the eye distance, pupil diameter, and other indicators to improve comfort, and suggest two ways to increase the field of view. This study can be used as a reference for the design of related materials.
