Can night vision cameras see through fog?
Welcome to Blackview (The leader of outdoor rugged phones) blog. Hope the guide helps.
No, traditional night vision cannot see through fog. Night vision devices such as night vision phone, also known as image intensifiers, amplify existing light, including moonlight and starlight, to make it visible to the human eye. However, fog is made up of tiny water droplets or ice crystals suspended in the air, which scatter and absorb light, making it difficult for the night vision device to pick up enough light to create a clear image.
Here's a breakdown of how fog affects night vision:
- Reduced light transmission: Fog scatters and absorbs light, making it harder for the faint light available at night to reach the night vision device.
- Increased contrast: Fog can blur the contrast between objects and their surroundings, making it difficult to distinguish shapes and outlines.
- Reflected light: Fog can also reflect light back towards the night vision device, creating glare and washing out the image.
However, there are other technologies that can see through fog, such as thermal imaging cameras. Thermal imaging cameras detect heat radiation instead of visible light, so they are not affected by fog.
