What does “resolution” refer to in NVG systems?

In night vision goggle (NVG) systems, "resolution" specifically refers to the ability to distinguish fine details in the image produced. This characteristic is crucial for the effectiveness of NVGs because it determines how clearly a user can see objects and recognize features in low light conditions. A higher resolution allows for greater clarity and the ability to discern smaller or more intricate details, which is essential for tasks such as identifying targets or navigating in dark environments.

While amplification of images, the range of visible light, and brightness levels are important factors in the performance of NVGs, they do not directly define resolution. The quality of the image in terms of how sharply defined objects appear is what fundamentally captures the essence of resolution in this context. This clarity can impact operational capabilities, making resolution a key specification when evaluating different NVG systems.
