One is a camera for recording objects seen in near-infrared light; it can detect galaxies otherwise obscured by dust.
However, near-infrared and visible light more easily penetrate the glass.
Furthermore, on April 30, 2009, two teams of scientists developed a cloak that rendered objects invisible to near-infrared light.
The cell structure of the leaves, on the other hand, strongly reflects near-infrared light (from 0.7 to 1.1 m).
The camera transmits invisible near-infrared light and measures its "time of flight" after it reflects off the objects.
For the non-selective heating is commonly used the near-infrared light, which penetrates more deeply into the tissue than others.
Although ship tracks can sometimes be visible, researchers usually scan the near-infrared light coming off the clouds.
The rich color range comes from the inclusion of invisible and near-infrared light.
These can be sound waves or beams of near-infrared light.
Images made with invisible, near-infrared light showed evidence of ancient caravan routes, undetectable on the ground, leading to and from one particular area.
