The thermal imaging temperature measurement gatekeeper uses an infrared detector, optical imaging objective lens, and optical scanning system (currently advanced focal plane technology eliminates the need for optical scanning systems) to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector. Between the optical system and the infrared detector, there is an optical scanning mechanism (not available in the focal plane thermal imager) to scan the infrared thermal image of the measured object, and focus it on the unit or spectral detector. The detector converts the infrared radiation energy into electrical signals, which are amplified, converted, or displayed as standard video signals through a television screen or monitor.
Infrared radiation is an electromagnetic wave that has the same essence as radio waves and visible light. The discovery of infrared radiation is a leap in human understanding of nature. The technology of using a special electronic device to convert the temperature distribution on the surface of an object into an image visible to the human eye, and displaying the temperature distribution on the surface of the object in different colors, is called infrared thermal imaging technology. This electronic device is called an infrared thermal imager.
Thermal imaging temperature measurement gatekeeper is a science that uses optoelectronic devices to detect and measure radiation and establish a mutual relationship between radiation and surface temperature. Radiation refers to the heat transfer that occurs when radiated energy (electromagnetic waves) moves without a direct conductive medium. The working principle of modern infrared thermal imagers is to use optoelectronic devices to detect and measure radiation, and establish a mutual relationship between radiation and surface temperature. All objects above absolute zero (-273 ℃) emit infrared radiation. The infrared thermal imager uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution pattern of the measured target and reflect it on the photosensitive element of the infrared detector, thereby obtaining an infrared thermal image, which corresponds to the thermal distribution field on the surface of the object.
Simply put, a thermal imaging temperature measurement gatekeeper converts the invisible infrared energy emitted by an object into a visible thermal image. The different colors on top of the thermal image represent the different temperatures of the object being measured. By viewing the thermal image, the overall temperature distribution of the measured target can be observed, and the heating situation of the target can be studied to determine the next step of work.
