Exploring the principles and discoveries of thermal imaging technology

Thermal imaging technology refers to the use of an infrared detector and optical imaging objective lens to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector, so as to obtain the infrared thermal image, which corresponds to the thermal distribution field of the object surface. Generally speaking, an infrared thermal imager is to convert the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the thermal image represent different temperatures of the measured object.

Although the low illumination camera can image in weak light, it becomes a decoration in a completely dark environment; The camera imaging by laser illumination can accurately reflect information about the object, but this technology depends on the light source illumination, so its application range is limited.

Principles of thermal imaging technology

Thermal imaging technology is based on the fact that all objects are hot. Although many objects can't be seen from the outside, there are still hot and cold on them. The temperature distribution can be seen with the help of the color on the heat map. Red and pink represent higher temperatures, while blue and green represent lower temperatures.

Discovery of thermal imaging

In 1800, an astronomer in Britain used a spectroscopic prism to decompose the sunlight into monochromatic light from red to purple and measure the thermal effects of different colors of light in turn. He found that when the mercury thermometer moved beyond the red light boundary and the human eye could not see any light in the dark area, the temperature was higher than in the red light area. Repeated experiments have proved that there is indeed an invisible "hotline" outside the red light, which was later called "infrared radiation", that is, "infrared radiation".

Infrared ray is ubiquitous in nature. Any object with a temperature higher than absolute zero (- 273.16 ℃) will emit infrared rays, such as ice.
