Types Of Night Vision Technology- 3 Types To Know


The night vision technology is one of the well-improvised advanced methods that help to provide the users with the perfect viewing of targeted objects even in the total dark conditions. The night vision technology helps to improve the vision in the low light state. There are different types of night vision technology used in imaging. Continue reading to know them.

Types Of Night Vision Technology

The night vision technology consists of three major types such as Low Light Imaging, Thermal Imaging, and Near Infrared Illumination. They are useful in various applications such as night security and surveillance purposes, night driving, search and rescuing process, flying and wildlife observation.

Low Light Imaging Process

Most of the night vision technology works based on the use of the image intensifiers implemented in the night vision goggles and night scope products. The image intensifier works on night vision by amplifying the available lighting condition for attaining the better vision display.

The lens focusses on to the photons of the image intensifiers, which further cause the electrons to affect the cathode accelerated by the electric field. This process helps to increase the speed of the device, to make the electrons entering the microchannel plates to create a dense cloud of the original image on the image intensifier phosphor screen.

The green phosphor screen is used in most of the applications as humans can differentiate green shades better than the other colors. The image intensifier is excellent for the low level of light sensitivity application such that it helps to enhance the visible imaging to the best possible extent. It constitutes of a high ability of resolution for the humans to trace out differentiations even in the low power state with an affordable cost.

Thermal Imaging Process

The thermal imaging process helps to estimate and detect the difference in the temperature between the object and the background. The thermal imaging works based on the principle of the microbolometer, which comes in two major types such as cooled thermal imaging camera and uncooled thermal imaging camera.

In general, the thermal imaging camera is widely used for different applications such as scientific research institute, R&D specialists, material testing, military defense purposes, and aerospace applications. The thermal imaging is based on the design, to uphold the high speed of motion for measuring the target objects with an accurate measure.

Infrared Illumination

The infrared illumination technology when combined with the infrared night vision, helps to estimate the sensitivity of the light. The infrared illumination helps to produce a high level of infrared lighting, to create the high resolution. This helps to enable the effective range of night time imaging even in the low light conditions such as residential, governmental, and security applications.

The infrared illumination is the low-cost technology when compared to the other night vision technologies. If you like this article, share it on social networking sites.
