What are the advantages of infrared thermal imager?

Infrared thermal imager uses temperature to image, and objects above absolute zero (-273℃) will emit infrared radiation. The infrared thermal imager uses an infrared detector and an optical imaging objective to receive the infrared radiation energy distribution map of the measured object and reflect it to the photosensitive element of the infrared detector, so as to obtain an infrared thermal image corresponding to the thermal distribution field on the surface of the object.

Infrared thermal imager has the following advantages:

1, strong concealment: passively receiving signals, not actively transmitting detection signals, not easy to be discovered by anti-reconnaissance means.

2. Strong penetrating ability: The penetrating ability of infrared thermal radiation to fog, haze, rain and snow is stronger than that of visible light, so the imaging effect of infrared thermal imager in bad weather conditions is almost unaffected. Especially, the long-wave infrared thermal imager acting on 8- 14um has stronger ability to penetrate fog.

3. All-weather working ability and strong light interference resistance: The infrared thermal imager generates scene images through the radiation of targets and backgrounds without the help of illumination light and ambient light, so it can work 24 hours a day and will not be interfered by strong light of visible light like other night vision equipment.

4, can identify hidden targets: ordinary camouflage is mainly to prevent visible light observation. Infrared thermal imager can detect hidden thermal targets through camouflage and grass leaves. The temperature and infrared radiation of human body and vehicles are generally much higher than that of vegetation, so it is not easy to disguise and make wrong judgments.

5. Fire monitoring and early warning: General fires are caused by obscure hidden fires. It is difficult to find this hidden fire sign in the existing conventional scheme. Because the infrared thermal imager is a device that reflects the surface temperature of an object, the infrared thermal imager is used to find the high-temperature point in advance and quickly find the ignition point through smoke, so as to know, prevent and extinguish the fire early.
