夜视镜所提供的视觉范围比在肉眼观察条件下的视觉范围（FOV）更为有限。因此，操作者必须连续地扫视周围环境以得到视觉信号。动态机敏度（DVA）是影响操作者能力，通过扫描克服视觉范围局限性的一个因素。本研究的目的在于提出用夜视镜测试DVA的方法，并记录在不同照明条件下 Night vision goggles provide more limited visual range than under visual inspection conditions (FOV). Therefore, the operator must continuously scan the surroundings to obtain a visual signal. Dynamic Sensitivity (DVA) is a factor that affects the operator’s ability to overcome the limitations of the visual range by scanning. The purpose of this study is to propose a method of testing night vision goggles DVA, and recorded in different lighting conditions
