What is Night Vision?
The night sight with image enhancer as the core device does not use infrared searchlights to illuminate the target when it works, but uses the light reflected by the target under weak light to enhance the visible image that can be felt by the human eye on the fluorescent screen through the image enhancer to observe and aim. aims. Infrared night vision is a military night vision instrument that uses photoelectric conversion technology. It is divided into active and passive types: the former uses infrared searchlights to illuminate the target and receives reflected infrared radiation to form an image; the latter does not emit infrared rays and forms a "thermal image" by relying on the infrared radiation of the target itself, so it is also called "thermal image" instrument".
Night vision
- The night sight with image enhancer as the core device does not use infrared searchlights to illuminate the target when it works, but uses the light reflected by the target under weak light to enhance the visible image that can be felt by the human eye on the fluorescent screen through the image enhancer to observe and aim. aims.
- Night vision equipment can be roughly divided into three categories:
- Observation mirrors-Observation mirrors are generally handheld, and can also be mounted on weapons. They use a single barrel (one eye) lens body. Since the scope is a handheld device and is not worn on the body like an eyepiece, it is more suitable when you want to observe a specific target in more detail and then return to normal observation conditions.
- In general, the use of night vision devices include: military, law enforcement,
- Compared with foreign countries, China's research on night vision started late. Beginning in the 1960s, with the joint efforts of the Shanghai Institute of Technical Physics, the Kunming Institute of Physics, and some universities in the Chinese Academy of Sciences, China's military field of night vision technology research has developed rapidly, but it is expanding to the civilian field The aspect has not been done well.
- Therefore, with the continuous increase of the number of night vision device manufacturers in China, the future night vision product research and development will focus on the civilian market, such as automotive night vision, camera night vision and other products will become the focus of future market development.
- As China's economy continues to grow at a high speed, the demand for the night vision device market in our country will increase significantly. We expect that the night vision device market will maintain a growth rate of about 15% in the next few years. Domestic brands will further achieve breakthroughs in product quality and technology. Occupy a larger market share. China's night vision equipment enterprises should grasp the development trend of the night vision industry when investing. Here are some of our suggestions:
- Night vision
- 1. Enterprises must further strengthen technology investment, improve production technology, reduce costs, and improve product quality. We recommend that Chinese enterprises introduce advanced technologies from foreign companies, digest and absorb on the basis of introduction, and then conduct independent research and development.
- Second, strive to improve the quality of the product, and work hard to improve equipment stability, performance parameters and life, reduce the failure rate.
- 3. Due to the diversified needs of different products, a series of night vision technology with different requirements are needed to respond to different needs of products, and companies need to work hard on product innovation.
- Fourth, pay attention to the development trend of products, such as the development trend of laser night vision, and invest in and develop products that meet industry development trends and market needs.
