In 1672, it was discovered that sunlight (white light) is composed of light of various colors. At the same time, Newton made a famous conclusion that monochromatic light is simpler in nature than white light. The use of a prism is used to decompose sunlight (white light) into monochromatic light of red, orange, yellow, green, cyan, blue, and purple. In 1800, British physicist F. W. Hell discovered infrared light when he studied various shades of light from a hot point of view. When studying the heat of various shades of light, he deliberately blocked the window of the dark room with a dark plate, and opened a rectangular hole in the plate, which was equipped with a beam splitting prism. When sunlight passes through the prism, it is broken down into colored bands, and a thermometer is used to measure the amount of heat contained in the different colors in the band. In order to compare with the ambient temperature, Herzl used several thermometers for comparison to measure the ambient temperature near the colored light strip. During the test, he stumbled upon a strange phenomenon: a thermometer placed outside the red light of the light, higher than the other temperatures in the room. After repeated trials, this so-called high-temperature zone with the most heat is always outside the red light at the edge of the light strip. So he announced that in addition to the visible light in the radiation emitted by the sun, there is a "re line" that is invisible to the human eye. This invisible "re line" is located outside the red light and is called infrared. Infrared is an electromagnetic wave with the same essence as radio waves and visible light. The discovery of infrared rays is a leap of human understanding of nature, opening up a new broad path for the research, utilization and development of infrared technology.
The wavelength of infrared rays is between 0.76 and 100 μm. According to the wavelength range, it can be divided into four types: near-infrared, mid-infrared, far-infrared and far-infrared. Its position in the continuous spectrum of electromagnetic waves is between radio waves and visible light. . Infrared radiation is one of the most extensive electromagnetic wave radiation in nature. It is based on the random movement of any object and its atoms in the normal environment. It constantly radiates thermal infrared energy, the movement of molecules and atoms. The more intense, the greater the energy of the radiation, and conversely, the smaller the energy of the radiation.
Objects with temperatures above absolute zero radiate infrared light due to their molecular motion. After the power signal radiated by the object is converted into an electrical signal by the infrared detector, the output signal of the imaging device can completely simulate the spatial distribution of the surface temperature of the scanned object in one-to-one correspondence, and is processed by the electronic system and transmitted to the display screen to obtain The corresponding thermal map of the surface heat distribution of the object. Using this method, it is possible to image and measure the temperature of the distant thermal state of the target and analyze and judge it.
The explosion-proof infrared thermometer adopts infrared non-contact temperature measurement mode, and the infrared light spot can be measured instantaneously on the target object in an explosive environment, and the use is fast and safe.
