- understanding night vision technology vs thermal imaging
Hello Everyone,
I have a thermal imager and I am interested in better understanding night vision (NV) technology. Apparently, NV goggles respond to NIR and SW
See this article. NV goggles can see from the near infrared (NIR) to the shortwave infrared (SWIR) portions of the light spectrum.
Do NV goggles work in complete darkness or always need some minimum level of ambient light (like from the moon)?
Why do the NV goggles capture NIR? The human body emits primarily in the far-infrared (FIR) which is detected and imaged by thermal imagers. I guess the human body emits also some NIR and SWIR...
Anyone with some experience with NV goggles?
Thanks for any comment.
