The distinction between thermal imaging and night vision
1. Effectiveness
1) If you've ever used regular night vision equipment, you'll notice that night vision equipment and regular infrared thermal imagers have very different observational sensations. This is so that the field of view observed is identical to that seen by the telescope lens, which is round and produces a green image, while the general night vision equipment directly examines the target through the lens. If the clarity is sufficient, it is feasible to recognize the character's intended audience as well as their target's distinct face traits.
2) The field of view is square because the infrared night vision thermal imager views the image on the internal LCD screen rather than the target directly. Based on the temperature distribution, the infrared night vision thermal imager will image. The brightness increases with increasing temperature. On the other hand, the hue gets darker as the temperature drops. Finding the target and identifying the target category—such as whether the target is a person, an animal, etc.—are the key goals.
2. The influence of light factors
1) Due to the imaging principle, the second-generation + night vision gadget is significantly impacted by the environment. Dimming the light will shorten the observing distance, especially when light is present. The usage of the supplementary infrared light source is required in the event of complete darkness, and its range is typically limited to 100 meters. While many conventional night vision equipment have powerful light shielding, they will also be terrified of intense light at the same time. However, a significant change in ambient brightness will have a significant impact on the observation.
2) Light will not harm an infrared thermal imaging night vision gadget. The target object can be seen clearly whether it's day or night, or if it's raining, snowing, or foggy outside. For this reason, high-end automobile night vision systems like Mercedes-Benz and BMW employ infrared thermal imagers.
