What is the main difference between the vision device and the thermal imaging night vision device?
1. In total darkness, thermal imaging night vision devices have obvious advantages
Since the thermal imaging night vision device is not affected by light, the observation distance of the thermal imaging night vision device is exactly the same in total darkness and normal light. The second-generation and above night vision devices must use auxiliary infrared light sources in total darkness, and the distance of auxiliary infrared light sources is generally only up to 100 meters. Therefore, in a very dark environment, the observation distance of the thermal imaging night vision device is much farther than that of the traditional night vision device.
2. In harsh environments, thermal imaging night vision devices have obvious advantages
In harsh environments such as fog and rain, the observation distance of traditional night vision devices will be greatly reduced. But thermal imaging night vision devices will be less affected.
3. In an environment where the light intensity changes greatly, the thermal imaging night vision device has obvious advantages
We all know that traditional night vision devices are afraid of strong light, although many traditional night vision devices have strong light protection. However, if the ambient brightness changes greatly, it will have a great impact on the observation. But the thermal imaging night vision device will not be affected by light. It is for this reason that top-of-the-line car night vision devices, such as those on Mercedes-Benz and BMW, use thermal imagers.
4. In terms of target identification ability, traditional night vision devices have advantages over thermal imaging night vision devices.
The main purpose of the thermal imaging night vision device is to find the target and identify the target category, such as whether the target is a human or an animal. The traditional night vision device, if the clarity is enough, can identify who the target is, and can see the facial features of the person clearly.
A Brief Introduction of Two Types of Night Vision Devices
Image-increasing tube night vision device: It is a night-vision device in the traditional sense, which can be divided into one to four generations according to the algebra of the image-increasing tube. Because the first generation of night vision devices cannot meet people's needs in terms of image brightness enhancement and clarity. Therefore, it is rare to see first-generation and first-generation + night vision devices abroad. Therefore, if you want to achieve real use, you need to purchase the second-generation and above image intensifier tube night vision device.
Thermal imaging night vision device: Thermal imaging night vision device is a branch of thermal imager. Traditional thermal imagers are more hand-held than telescope-type, and are mainly used in traditional engineering inspections. At the end of the last century, with the development of thermal imaging technology, the U.S. military gradually began to equip thermal imaging night vision devices due to the technical advantages of thermal imaging technology over traditional night vision devices. Thermal imaging night vision device, another name is thermal imaging telescope, in fact, it can still be used very well during the day, but because it is mainly used at night to exert its effectiveness, it is called thermal imaging night vision device. The thermal imaging night vision device has been continuously developed in the past 10 years, and RNO, a well-known military enterprise in the United States, can say that it has contributed a lot. The cooperation between RNO and the US military has also promoted the development of thermal imaging night vision devices for civilian use. RNO's HC series of thermal imaging night vision devices can be said to be well-known in the US military. The popularity is very high.
