Analysis of the Seven Natural Advantages of Today's Thermal Imaging Technology

In the all-weather monitoring arena, in addition to thermal imaging in the accumulation of fine storage, low-light, laser lighting and infrared lights and other technologies have also set up camps, and share the day-night surveillance front-end market. However, Ichikawa Kei, head of the company's new business promotion office, said that although low-light cameras can be imaged under faint light, they have become furnishings in a completely dark environment; cameras that are imaged by laser light can accurately reflect the subject. The information, but the technology relies on light source lighting, so the application range is subject to certain restrictions; the near-infrared camera is also an active type camera, but it often appears to be very poor in terms of service life and irradiation distance. Shen Chen’s Chen Daming also stated that infrared thermal imagers have an irreplaceable absolute advantage over technologies such as low illumination, laser illumination and infrared lamps:

1, the role of distance. General infrared lamp products have less than 100 meters of imaging distance. The thermal imager images the infrared radiation emitted by the object and is not limited by the ambient light and the illumination light. In general, the telephoto thermal imager can observe more than 3 kilometers of people and more than 6 kilometers of vehicles.

2, hidden and strong. It is completely passively receiving signals and does not actively transmit detection signals, which is not easily detected by anti-reconnaissance methods.

3, strong penetration. Infrared heat radiation has a stronger ability to penetrate fog, haze, rain, and snow than visible light, and thus the imaging performance of the infrared thermal imaging system under severe weather conditions is hardly affected. Especially for long-wave infrared thermal imager with 8-14um, it has stronger penetrating mist ability.

4, all-weather work ability, anti-glare interference. Infrared thermal imager imaging does not rely on illumination and ambient light, but on the object and background radiation to produce scene images, so infrared thermal imaging system can work 24 hours a day, and will not be as visible light as other night vision devices interference. Low-light cameras cannot image without ambient light.

5, can identify hidden targets. Common camouflage is based on preventing visible light observations. The crimes committed by ordinary criminals are usually hidden in the grass and forests. Due to the harsh environment and human visual illusions, it is easy to make erroneous judgments. Infrared thermal imaging can detect camouflaged thermal targets through camouflage and tussock leaves. The temperature and infrared radiation of humans and vehicles are generally much larger than the temperature and infrared radiation of vegetation, so it is not easy to disguise and it is not easy to make erroneous judgments.

6, fire monitoring. Normal fires are caused by unobvious hidden fires. With existing common methods, it is difficult to find such hidden fire signs. Since the infrared thermal imager is a device that reflects the surface temperature of an object and is imaged, an infrared thermal imager is used to find a fire point through smoke, so that early warning can be prevented and extinguished as early as possible.

7, low power consumption and long life. Laser lighting or infrared lamps need more active power because of the need for active lighting. In some special power applications, low-power infrared camera systems must be used. Since the thermal problems of active systems such as infrared lamps are not well solved, and the life of ordinary infrared lamps is only 1000 hours, the life of laser lighting is about 10,000 hours, but the life of uncooled infrared thermal imagers can reach 45,000 hours.
