Principle and performance advantages of infrared thermal imager
- 2019-06-06-

Infrared thermal imaging technology has applications in both the military and the civilian world, beginning with military use and gradually turning to civilian use. It is generally called a thermal imager in civilian use, and is mainly used in research and development or industrial inspection and equipment maintenance. It is also widely used in fire prevention, night vision, and security.

The thermal imager uses the infrared detector and the 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 to obtain an infrared thermal image. This thermal image and the thermal distribution of the surface The field corresponds. Generally speaking, a thermal imager is to convert invisible infrared energy emitted by an object into a visible thermal image. The different colors on the top of the thermal image represent different temperatures of the measured object.

Infrared thermal imager uses infrared detector, optical imaging objective lens and optical-machine scanning system (the current advanced focal plane technology omits the optical-machine scanning system). The infrared radiation energy distribution pattern of the measured target is reflected to the infrared sensitivity Originally, between the optical system and the infrared detector, there is an optical-mechanical scanning mechanism (the focal plane thermal imager does not have this mechanism) to scan the infrared thermal image of the measured object and focus on the unit or spectroscopic detector. The infrared radiation energy is converted into an electric signal by a detector, and the infrared thermal image is displayed by a television screen or a monitor after being amplified, converted or a standard video signal.

Comparative advantages of infrared thermal imager and traditional temperature measurement method

Not easy to miss when detecting smaller targets

High detection efficiency, advanced non-destructive testing technology, can analyze the overall temperature distribution of the target

For equipment inspection, equipment inspection, and equipment management, do a good job of equipment maintenance and equipment maintenance planning to achieve predictive maintenance in advance. Infrared cameras are still your good helpers.
