The main feature of the thermal imaging camera is that it can display the temperature of the object being measured, and depending on the temperature, it can also present different images. Generally divided into industrial temperature measurement type and observation type. Widely used in steel, coal, electric power, investigation, fire, and other fields.
The thermal imaging camera is the use of infrared detectors and optical imaging objective lens to accept the infrared radiation energy distribution of the target to be measured graphically reflected in the infrared detector's photosensitive element, so as to obtain the infrared thermal image, this thermal image corresponds to the object surface heat distribution field.
In layman's terms, a thermal imaging camera transforms the invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent the different temperatures of the object being measured.
Extended information:
Modern thermal imaging cameras work by using optoelectronic devices to detect and measure radiation and establish a correlation between the radiation and the surface temperature. All objects above absolute zero (-273°C) emit infrared radiation.
The thermal imaging camera utilizes an infrared detector and an optical imaging objective to accept a graphical representation of the energy distribution of the infrared radiation from the target under test, which is reflected on the photosensitive element of the infrared detector, resulting in an infrared thermogram that corresponds to the heat distribution field on the surface of the object.
The ability of a thermal imaging camera to distinguish small temperature differences affects the degree of detail of the image. The higher the sensitivity, the better the imaging, and the better the ability to distinguish the exact location of the point of failure.
