When it comes to night vision devices, most people think of image intensification technology. In fact, image intensification systems are generally referred to as night vision devices (NVDs.) Inside the NVD is an image intensifier tube that can be used to capture and amplify infrared and visible light. Here's how an image intensification system works:A conventional lens called an objective lens captures ambient light and certain near-infrared light.The collected light is transmitted to the image intensifier tube.

The differences between infrared thermography and low-light imaging are as follows:1. Imaging Principle:Infrared Thermography:It captures the infrared radiation emitted by objects and converts it into visible images. All objects above absolute zero emit infrared radiation, which can be detected and used to create a temperature distribution map, displaying the thermal image of the object. This technology does not require external light sources and can work in completely dark environments.Low-light Imaging:It relies on amplifying extremely weak ambient light, such as moonlight or starlight.

To understand the principles of night vision, it is necessary to know something about the principles of light. The amount of energy in a light wave is related to its wavelength: the shorter the wavelength, the higher the energy. In visible light, violet light has the highest energy, while red light has the lowest. Adjacent to the visible light spectrum is the infrared spectrum.

How to buy a good enough night vision device?Now, we start to share with you some dry facts to help people who wish to buy a night vision device to buy one that meets their requirements.Classification of night vision devices:First of all, Night Vision Devices (Night Vision Devices) are categorized into Infrared Night Vision (Infrared Night Vision), Laser Night Vision (Digital Night Vision) and Shimmer Night Vision (Image Intensifier). After testing these three types we can tell you with confidence that the Microlight Night Vision is the only night vision device worth buying.

The 14th Jordan (Aqaba) International Defense and Uniformed Services Exhibition was held on September 3-5, 2024 at the Aqaba International Exhibition Center. It is the largest and most authoritative military, police and defense exhibition in Jordan.Jovstar focuses on displaying portable multi-functional thermal imaging cameras, gun sights, micro-light night vision devices and other products to global customers.

Infrared night vision device is the use of photoelectric conversion technology of military night vision device. It is divided into active and passive two kinds: the former with infrared searchlight irradiation target, receive reflected infrared radiation to form an image; the latter does not emit infrared, relying on the target's own infrared radiation to form a “thermal image”, so it is also known as the “thermal imaging camera”.Visible light at night is very weak, but infrared light, which is invisible to the human eye, is abundant.

From January 16 to 18, 2024, the 25th Middle East (Dubai) International Security Equipment and Technology Exhibition (Intersec Dubai) in Dubai World Trade Center (DWTC) concluded perfectly, 1,000 exhibitors from more than 60 countries and regions to display their latest products and technological achievements in the field of security.Jovstar with “AI + security” as the core, relying on artificial intelligence, cloud computing, big data and other new generation of information technology, to the global customer focus on portable multi-functional thermal imaging camera, gun sights, micro-light ni

To better ensure the normal operation of society, the installation of surveillance is essential, but the installation of a traditional visible light surveillance without image enhancement can become difficult when forensic review and video analytics performance is required, so it is possible to install a thermal imaging camera with 7 × 24 monitoring in some important occasions.Both plants, animals, humans, cars and objects emit heat. The defining characteristic of a thermal sensor is the detection of heat in response to small differences between thermal features in the image.

Night vision equipment can be roughly categorized into three main groups:Spotting scopes - Spotting scopes are generally hand-held and can also be mounted on a weapon, they utilize a monocular (one eye) body. Since spotting scopes are handheld devices and are not worn on the body like eyepieces, they are more suitable when you want to take a more detailed look at a specific target and then return to normal observation conditions.Eyepieces - Although eyepieces can also be handheld, they are usually worn on the forehead.

According to “infrared diagnostic application specification for energized equipment DL/T 664-2016” there are six kinds of infrared defect determination methods:1. surface temperature judgment methodIt is mainly applicable to current-heated and electromagnetic effect-heated equipment.
