Night vision fusion devices have become the new standard for nocturnal operations and are being applied in various sectors, including the military, emergency services, and increasingly in the hunting field. Certain challenges can only be addressed by combining the two leading night vision principles: image intensification (light amplification) and thermal imaging. Image intensification provides a basic representation of the surroundings, over which the fusion device overlays a thermal image. Due to its capability to integrate data from various spectral ranges, fusion devices can offer a more comprehensive and informative view of the environment. This is especially valuable in situations where traditional night vision devices fall short, such as when clear detection is required.
