What is the difference between thermal imaging and night vision?

Thermal imaging and night vision are two distinct technologies used for different purposes. Thermal imaging uses thermal energy or infrared radiation emitted by objects and converts it into a visible image. It detects temperature variations and can capture images in total darkness, as it doesn't rely on ambient light. This allows for effective detection of hidden objects, identifying heat leaks, and seeing through smoke or fog. On the other hand, night vision amplifies existing visible light to improve nighttime visibility. It requires some level of ambient light, such as moonlight or starlight, to produce an image. Night vision is commonly used in low light conditions to enhance the clarity and detail of the scene, making it useful for activities like surveillance, hunting, or navigation. In summary, thermal imaging detects thermal energy, while night vision requires a minimal amount of existing light to produce an image. Both technologies have unique applications and offer distinct advantages depending on their intended use.
