Humans have relied on snakes to invent a range of infrared imaging devices.
Infrared rays are invisible to the human eye, but snakes are equipped with a thermal eye that can sense infrared rays, located between the snake's eyes and nostrils. The nerve endings on the thermal eye sense the infrared radiation from the target will immediately generate a bioelectric current, which is transmitted to the snake's brain, which, after analyzing it, can determine the approximate shape of the object that exists in front of it, and then make the action of capturing or avoiding it.
People have invented a series of infrared imaging devices based on the snake's infrared perception principle, which can detect infrared rays radiating from the surface of an object that are not visible to the human eye, and thus determine the distribution of the temperature field on the surface of the object.
Because the atmosphere absorbs infrared energy, infrared detection equipment often utilizes infrared wavelengths such as near-infrared (0.76-1.1 μm), mid-infrared (3-5 μm), and far-infrared (8-14 μm), which are also referred to as the infrared spectra of the "three atmospheric windows".
Infrared rays
The most significant effect of infrared rays is the thermal effect, so infrared rays can be used to heat objects, drying paint and grains, medical treatment, and so on. Infrared rays easily pass through clouds of smoke and dust, so infrared-sensitive negatives can be utilized for long-distance and high-altitude photography.
All objects, including the earth, clouds, the human body, airplanes and ships, are constantly radiating infrared rays, and different objects radiate infrared wavelengths and intensities are different, the use of sensitive infrared detectors to absorb infrared rays emitted by the object, and then processed by electronic instruments on the received signals, you can be detected by the characteristics of the object being probed. This technology is called infrared remote sensing technology.
Using infrared remote sensing technology, can be on the aircraft or satellite survey geothermal, looking for water, monitoring forest disasters, estimate the growth of crops or harvest, forecasting typhoons and cold waves, etc.. The application of infrared remote sensing technology is developing rapidly.
