Principle and function of infrared imager

The infrared camera uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution pattern of the target to be reflected on the photosensitive element of the infrared detector, thereby obtaining an infrared thermal image, the thermal image and the surface heat of the object. The distribution field corresponds. In general, an infrared camera converts invisible infrared energy emitted by an object into a visible thermal image. The different colors above the thermal image represent the different temperatures of the object being measured.

An infrared camera is a science that uses optoelectronic devices to detect and measure radiation and establish a correlation between radiation and surface temperature. Radiation refers to the movement of heat that occurs when radiant energy (electromagnetic waves) moves without direct conduction of the medium. Modern infrared cameras work by using optoelectronic devices to detect and measure radiation and establish a correlation between radiation and surface temperature. All objects above absolute zero (-273 ° C) emit infrared radiation. The infrared camera uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution pattern of the measured object and reflect it on the photosensitive element of the infrared detector, thereby obtaining an infrared thermal image, the thermal image and the heat distribution on the surface of the object. The field corresponds. In general, an infrared camera converts invisible infrared energy emitted by an object into a visible thermal image. The different colors above the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the target can be observed, and the fever of the target can be studied to judge the next step. Humans have been able to detect infrared radiation. The nerve endings in human skin can respond to temperature differences as low as ±0.009 ° C (0.005 ° F). Although the nerve endings of the human body are extremely sensitive, their construction is not suitable for non-destructive thermal analysis. For example, although humans can find warm blood prey in the dark with the thermal perception of animals, it may still be necessary to use better thermal testing tools. Due to the physical structural limitations of humans in detecting thermal energy, mechanical and electronic devices that are very sensitive to thermal energy have been developed. These devices are standard tools for checking thermal energy in a wide range of applications.
