Understanding The Subtle Relationship Between Thermal Imagers And Night Vision Devices
With the development of science and technology and the opening of national policies, legal hunting has gradually become a new type of outdoor entertainment. There are many military fans and outdoor enthusiasts who have a growing demand for thermal imagers and night vision devices. At the same time, many netizens with a strong thirst for knowledge are asking: What exactly are thermal imagers and night vision devices?
Today, pay attention, our knowledge lecture is open!
In short, thermal imagers and night vision devices are high-tech equipment that can provide you with high-definition imaging in the dark, and can easily obtain clear target images in a completely dark environment.
At present, they have been widely used in military security, industrial technology, automobile assisted driving, epidemic prevention inspection, forest fire prevention, outdoor hunting and medicine.
So what is the difference between thermal imagers and night vision devices? Read on:
Thermal imagers are passive infrared, which relies on receiving infrared energy (temperature/heat energy) emitted by the object itself, and then presents it through the display after receiving and processing.
The resulting image has multiple display modes. For example, PARD Technology's thermal imaging products have five image modes: red-hot pseudo-color, white-hot, black-hot, iron-red pseudo-color, and sky. Thermal imaging does not rely on itself to emit infrared rays, but only receives infrared rays from the outside world.
Night vision devices are active, which means that light must be reflected on objects and the night vision device receives the image. Night vision devices in the civilian range are usually digital night vision devices, which can be used both day and night. Under good lighting conditions during the day, the imaging effect is clearer, and some products can present color images.
At night, under the conditions of external light sources or self-filling lights, most of the images are black and white. In a completely dark environment, PARD Technology's digital night vision products can provide high-definition night vision images within an infrared range of 350m.
So from the perspective of outdoor hunting needs, how to choose thermal imaging devices and night vision devices? The following will provide a simple answer for friends with entry-level needs:
In the night hunting environment, night vision goggles are used to observe the target. The distance that can be observed is relatively close, and the imaging effect is closer to the actual appearance of the observed target itself, but there are certain limitations, that is, the target is easily confused when it blends into the environment and is not easy to find.
However, its imaging is more realistic, and the actual appearance and outline of the object can be observed from a certain distance, and its price is relatively cheap, so friends with a low budget can choose night vision goggles.
In comparison, the detection distance of thermal imagers is farther, and it uses the principle of thermal imaging, using temperature difference to distinguish between heat sources and surrounding environmental interferences, so it is easier to find the existence of the target. However, its price is generally more expensive, and the entry threshold is higher.
Finally, to sum up, there is no difference between the two products, it depends on your needs and budget. Here, I also wish every viewer can find a thermal imaging night vision product that suits him or her and that he or she likes.
