Night vision has always been one of the subjects of fascination and interest in us humans. We have always dreamed of being able to see in complete darkness, overcoming the limitations of nature. The invention of infrared (IR) lighting became one of the revolutionary technologies that changed our perception of darkness and opened up new possibilities in various fields of activity. Let's look at the history of IR night vision and its importance in today's world.
The history of night vision has ancient roots and began with human observations of natural light sources such as the moon and stars. In ancient times, people used lights as a light source for night vision. However, this method was limited, as fire caused difficulty in maintaining stealth and making objects visible.
The first significant step in developing night vision was the creation of optical tubes during the First World War. The sight tubes were a big step forward, allowing the military to see objects in low light using available light from the moon and stars. However, these devices were far from ideal because their efficiency was limited, and they could not work in absolute darkness.
Over the years, night vision technology has gradually improved. In the 1930s, German and British scientists began to explore the possibilities of infrared radiation for displaying objects. Infrared radiation, which is not visible to the human eye, has excellent potential for creating night vision systems.
A breakthrough in the development of technology came during the Second World War. Scientists and engineers began to actively work on creating infrared cameras and devices for military needs. These infrared systems made it possible to see the thermal radiation of objects, which was especially useful for detecting enemy troops at night.
In this article, we have provided a detailed overview of night vision technology using IR illumination, its impact on various industries and people's lives, and advice on the right choice of devices with this technology. Infrared illumination has become an indispensable tool that has revolutionized how we see in dark and low-light conditions. This technology has opened up new opportunities in industries such as military, police, security, hunting, scientific research, photography, and home security.
With the help of infrared illumination, people can see objects and events that previously remained invisible in the dark. The imprint of this technology is felt in various aspects of our lives, where it brings benefits and security.
What is it?
IR night vision is a technology that revolutionizes our perception of darkness and is an essential tool in many areas of life. For a better understanding of the principle of operation of this technology, let's consider the main aspects of its operation.
IR illuminators use infrared rays, which have a wavelength outside the visible spectrum of light for the human eye. The basic idea is that these infrared rays are invisible to the naked eye but help improve objects' visibility in dark or low-light conditions. When the IR illuminator is activated, it emits infrared light that is invisible to the observer but helps to illuminate the environment.
One key element of IR illuminators is infrared LEDs (IR LEDs). These LEDs are specially designed to emit infrared light and are used in many devices such as night vision binoculars, surveillance cameras, video recorders, etc.
The IR illuminator's operation principle is that infrared light emitted by LEDs is reflected from surrounding objects and returned to the device. Sensors decide the distance to things based on the time it takes for light to travel that distance. This allows the device to create images of objects ordinarily invisible in the dark.
Applications of IR illumination are diverse. From military operations and police surveillance to use in home security systems and photography in the dark, this technology has become an integral part of the modern world. It is essential to know that IR illumination is not limited to military or law enforcement purposes. It is also used in science, conservation, and search and rescue operations.
In light of the expansion of IR illumination over the years, this technology has been applied in many industry and everyday life areas. Now that we've covered what an IR illuminator is and how it works let's move on to the different types of IR illuminators and their features in the next part of the article.
